WARNINGFailure to follow these installation instructions could cause FIRE, CAR-BON MONOXIDE POISONING, and OR DEATH. If you are unsure of instal-lation requirements, call the phone number listed on the front page ofthis manual.

Suitable for positive pressure venting application withmaximum 15’’ water column internal static pressure at 550°F.

General Notes:Use only factory-supplied components. Failure to do so will void thecertification and the warranty of this vent.In areas with continuous temperatures below -18ºC (0ºF) the use of anexterior vent systemmay result in operating problems such as poor draftand excessive condensation of combustion products. If you do install anexterior vent, we recommend that you install a double wall insulated sys-tem model HEPL or HEPL2.

Maintenance Notes:Vent Cleaning: Other than for standard natural gas system applicationswhere minimal maintenance is necessary. Keep your vent clean. Accessshould be provided for the inspection and cleaning of all sections of thevent. Have your system cleaned by a qualified vent system sweep. If youwant to clean the vent yourself, clean with a nylon or metal system brushof the correct size. Do not use a brush that will scratch the stainless steelinterior of the vent system.

UNDERWRITERS LABORATORIES LISTINGS:CHEMINÉE LINING.E inc. venting systems models HEP, HEPL

and HEPL2 are listed by Underwriters Laboratories inc. (UL)under file MH 10081 and tested in accordance with UL1738Standard for Venting Systems for Gas-Burning Appliances, cat-egories II, III and IV and the Canadian standard for type BH gasventing systems ULC-S636-95. Listings include the followingvent product categories and diameters:

UL 1738Model Classification Diameters

HEP • HEPL • HEPL2 Gas-Burning Appliances 550°F 6” to 48” I.D.

CAN / ULC-S636-95Model Classification Diameters

HEP • HEPL •HEPL2 Type BH Gas Venting 550°F 6” to 48” I.D.

FEATURESModels HEP, HEPL and HEPL2 are part of the Industrial Positive

Pressure products for industrial and commercial applications.They are prefabricated modular venting systems designed forquick assembly and using the same plasma-weld stainless steelinner wall. Given that all parts have a male and a female end,each model part fit into one another, thus eliminating the needfor all kinds of adapters. This unique method of coupling pro-vides an incomparable flexibility in selecting models of ventingsystem. Model HEP is a single wall construction, model HEPL isa double wall construction with 2” air space between walls andmodel HEPL2 is also a double wall construction, but with 2”of mineral fiber insulation. The high quality of stainless steelinner wall construction using a plasma-welded method for thelongitudinal joint provides a high strength-to-weight ratio andlow friction losses.

APPLICATION

UL 1738

1. Venting Systems for Gas-Burning Appliances,Categories II, III, and IV (550° Vent Listing) – Under this cat-egory, models HEP, HEPL and HEPL2 have been determined suit-able for venting flue gases at a temperature not exceeding288°C (550°F) above ambient, under continuous operating con-ditions, from gas, liquid, oil or solid fuel fired appliances.2. Positive Pressure Listing – These models are rated for

use at a maximum of 15 inch water column internal pressurewhen used in a positive pressure application.

CAN / ULC-S636-95

3. Standard for Type BH Gas Venting Systems (550°Chimney Listing) – Under this category, models HEP, HEPL andHEPL2 have been determined suitable for venting flue gasesat a temperature not exceeding 288°C (550°F) above ambient,under continuous operating conditions, from gas, liquid, oil orsolid fuel fired appliances.

SURROUNDINGS/ENCLOSURES1. Models HEP, HEPL and HEPL2 venting systems are prima-

rily intended to be installed in fire resistive, non combustiblesurroundings or in unenclosed installation. They are notintended for use in one or two-family dwellings. (CAUTION: Do

not enclose this venting system in chase or passageway madeof wood or other combustible material.)2. Where the venting system extends through any zone of

a building outside the area in which the heating appliance con-nected to it is located, it shall be provided with an enclosurehaving a fire resistance rating equal to or greater than the firerating of the floor, wall or roof assemblies through which itpasses.3. Models HEPL and HEPL2 venting systems may penetrate

a combustible roof or wall using the Ventilated Roof Flashingassembly. For wall penetrations, the use of the Wall Firestopassembly is required. This is the only part intended for usewith combustible construction. All other parts, such as AnchorPlate and Wall Support, Wall Guide and Floor Guide are forattachment to non-combustible construction.4. Where, according to local code, no chase enclosure is nec-

essary, models HEP, HEPL and HEPL2 may be placed adjacent toor in a corner made of walls of combustible construction at theclearance specified on each vent section and in the individuallisting; see “CLEARANCES”. Contact local building or fire offi-cials about restrictions and installation inspection in your area.

SYSTEM SIZINGComplete system sizing and capacity may be obtained from

the “Chimney, Gas Vent, and Fireplace Systems” chapter of theASHRAE Handbook or contact your CHEMINÉE LINING repre-sentative. In spite of any sizing guidelines, when sizing vent-ing systems, it is most important that the appliance manufac-turer’s installation instructions be followed. Not following theseinstructions may result in inadequate vent system performanceand/or a violation of the equipment manufacturer’s installationrequirements. Proper operation of the venting system and appli-ance is dependent on the use of all parts specified by the man-ufacturer for use in the particular installation. The performanceof the system may be affected if the proper assembly of allrequired parts is not accomplished.

SUPPORT METHODS AND HEIGHT LIMITS1. Several support and guiding methods are used to anchor

a vent against upward, downward and angular displacement.2. These supports and guides used with thermal expansion

devices prevent bending stresses on the vent system elbowsand joints.3. Supports and guiding installation methods are described

in Section C. Certain limitations apply for proper installationof supports and guides. See Table A-5 and A-6.

VENT GUYING AND SPACING1. Proper guying and bracing is essential for part of the vent

system that extends above the roof or a parapet wall. The ventat this point is subject to wind conditions and needs specialattention for proper stabilization.2. For low freestanding installations the system needs no

special guying or bracing if overall height between the roof sup-port and the top of the vent is no greater than 10 feet. SeeFig. A-5 for detail.

3. For above the roof installations where freestanding heightlimits are exceeded, cables or bracing are needed to resist heavywind conditions and effects and prevent structural damage.Rigid bracing can be used where system height above roof isrelatively low.4. Roof Band assembly (RB) part is used for rigid bracing in

above the roof installations. Guy Wire Band (GWB) model canalso be used as an option, instead of the roof band assembly.5. In addition to the roof support where freestanding height

is exceeded, the vent needs to be secured below the roof witha support to protect the roof flashing against additional loadscaused by wind on the exposed vent system. (See Fig. A-6).

4. When elbows are used for offsets in the main vertical por-tion of the vent, caution should be exercised to prevent exces-sive bending forces and/or design problems. (See OFFSETS inthis Section for details)

5º ELBOW (E5)1. Used for offset or deviation of the horizontal part of the

vent system by 5º.2. May be used to slope a vent to facilitate the run-off of

condensation water from the vent system. (See Fig.B-7b)

Any horizontally installed portion of a venting system shallhave a slope (upwards for Category II, III or IV appliances ordownwards for Category III or IV appliances) not less than 1/4inch (6.4mm) every 12 inches (305mm) to prevent collection ofcondensate at any location in the assembly.Means shall be provided for draining the condensate. Due to

ice build up and blockage, it is required that the proper slop-ing be employed when the vent is installed in a horizontal instal-lation. Refer to the appliance manufacturer’s installation instruc-tions for further details regarding the installation of thecondensate drain fittings.

15º ELBOW (E15)Used for offset or deviation of the vent by 15º.

30º ELBOW (E30)Used for deviation of the vent by 30º.

OFFSETS1. Except where absolutely necessary, sloped or horizontal

offsets in the vertical portion of a system above the breechingshould be avoided.2. Because elbows (and fittings) can only take limited forces

due to any bending moments, special care should be exer-cised in designing the bracing for elbows.3. Structural parts such as posts or beams may also be

needed to hold vent supports in position.4. Vent system for combination fuel heating appliances that

are capable of burning solid fuel or are convertible to solidfuel are limited to the same 30º slope even if the current choiceof fuel is gas or oil.5. The length of offset, if one is necessary, is determined

by strength considerations. The maximum dimension betweensupports, given as the “MHS” dimension in Section A of theseinstructions, is applicable to all horizontal and sloped orienta-tions. (See Fig.B-8)6. With frequent resupport, there is no structural or oper-

ating limit to the length of horizontal or sloped portions of amodels HEP, HEPL or HEPL2 vent, providing the system meetsthe capacity, pressure drop of available equipment.7. The carrying capacity of models HEP or HEPL2 supports

and their structural attachments must take into account theweight of the offset plus whatever vertical pipe is carried bythat support.8. Height limits for supports are tabulated in Section A of

these instructions.9. The ends of any sloped or horizontal offset must be

anchored to prevent overstressing elbows.10.The vertical sections of system above the offset must also

be supported or anchored and guided where necessary.11.Models HEP, HEPL or HEPL2 Roof Support (RS), Wall

Support (WS), Wall Guide (WG) may be used in a variety of waysfor offset support to achieve the structural stability of the ventsystem. Preferred methods of using models HEP, HEPL or HEPL2supports are shown in Section C.

12.Resupports such as those shown in Fig.B-8 must besecurely anchored to walls, posts, or locally fabricated rigidframework. This framework must be designed to assure sta-bility of attached models HEP, HEPL or HEPL2 supports, suchas Anchor Plate (AP) supports and Wall Supports (WS).13.Supports suspended by threaded rods or from small size

angles or straps are usually not satisfactory to resist bendingmoments due to offsets.

SPECIAL PARTSAvailable when specified are special parts or components

used in vent systems that can be factory-built to accommodatefield situations where standard parts cannot be used.

FLAT FLASHING ASSEMBLY (F)The Flat Flashing assembly (F) is primarily used for boiler or

low temperature exhaust where a vent section passes througha roof made of combustible material. It is designed to beinstalled on a flat roof curb of a minimum height of 12” (SeeFig. D-1). For some areas, greater heights may be neededaccording to local code requirements.The roof framing dimension must provide sufficient open-

ing to comply with the minimum clearance from combustibles.(See Section A for minimum clearance)The Roof Support (RS) is secured to the top of the roof curb

using two 1/4” x 2 1/2” inch lag bolts in each support bracket.(See Section C for detail of Roof Support (RS)). The Flat Flashing(F) is then lowered on to the curb and the Storm Collar (SC)secured to the vent system section with the screws supplied.A Ventilated Flashing (VF) option is also available where air

circulation between the system and the roof structure is wanted.The Ventilated Flashing (VF) option may serve as a ventilationoutlet in small boiler rooms with gravity air supply.

*Notes: 1. May be used in non-combustible roof application, See Section A

Table-A-3 for roof openings.

2. Framing of roof openings for combustible roof applications must

meet specified clearances in Section A Table-A-3. Proper framing is

the responsibility of the installing contractor.

FLAT FLASHING (F) WITHOUT ROOF CURBThe Flat Flashing (F) assembly is primarily used for low tem-

perature exhaust where a vent section passes through a roofmade of non-combustible material.

INSTALLATION1. Install roof curb over the roof opening.2. Install the Guiding Spacer (GS) on the vent system sec-

tion passing through the roof to allow for expansion of the sys-tem section by allowing it to slide in the Insulated Sleeve (IS)assembly.3. Install Insulated Sleeve (IS) by sliding it in over the guide

and vent section. Secure the sleeve to the roof curb with themounting brackets or the Roof Support (RS).4. Install the Ventilated Flashing (VF) over the roof curb

and Insulated Sleeve (IS) assembly.5. Install the Ventilated Collar (VC) by securing it to the pipe

section leaving a 4” gap between the collar and the top of theVentilated Flashing (VF).6. Install the firestop by sliding it over the Insulated Sleeve

WALL PENETRATION1. Where a vent system section passes through a wall, the

combustible material in the wall need to be protected from radi-ation heat from the system.2. Table-D-1 shows the different parts that provide sufficient

clearance between the vent and the combustibles in the wall.3. Table-D-1 also shows required clearance between the

vent system and the combustibles as well as the wall openingneeded for each system model.

WALL FIRESTOP (WFS)The Wall Firestop assembly (WFS) is primarily used for wall

penetration allowing a section to pass through a wall made ofcombustible material. It is used to maintain a minimum clear-ance between the combustible wall material and the vent sec-tion passing through the wall.

INSTALLATION FOR EXTERIOR WALL1. From Table-D-1 (in this section) determine the wall open-

ing for the system model to be installed.2. From the interior wall side, put the Wall Firestop (1)(WFS)

in place before passing the pipe section in the opening. (SeeFig.D-3 and D-4).3. From the exterior wall side, slide theWall Firestop (2)(WFS)

in the opening and secure to the exterior wall with anchors(by installer).4. From interior wall side, secure Wall Firestop (1)(WFS) to

inside wall with anchors (by installer).

INSTALLATION FOR INTERIOR WALL1. From Table-D-1 (in this section) determine the wall open-

ing for the vent model to be installed.2. Repeat steps 2, 3 and 4 as described in exterior wall instal-

lation.

FIRESTOP (FS)Used to maintain a minimum space between any combustible

material of a wall, floor or roof, where a vent system passesthrough.

RADIANT FIRESTOP (RFS)Used to protect combustible materials where a system passes

through a floor, ceiling or attic. It ensures a minimum distancefrom combustible materials.

RAIN CAP (RC)Installed at the top of the vent, it prevents entry of rain into

the vent system. (See Fig.E-11 for assembly)

EXHAUST CONE (EC)Installed at the top the system, it improves the draft and

increases the speed of escaping gases by 50%. Installation ofa Drain-Tee Cap (DC) at the base of the vent is required to col-lect rainwater. For installation details Exhaust Cone (EC) (SeeFig.E-11).

CLOSURE SECTION (CS)Installed at the vent system extremity. It protects the system

against water infiltration in the insulation between the innerand outer wall of the system. The use of Drain Section (DS) orDrain Tee Cap (DC) is necessary with this piece to collect anyexcess rain that may penetrate the vent.

STORM COLLAR (SC)Used for sealing the opening between the vent and flashing.

The Storm Collar (SC) must be sealed to the vent system withsilicone putty. It is supplied with the Flat Flashing (F) roof assem-bly or Adjustable Flashing (AF) roof assembly.

MITER SECTION (MS)Installed at the system extremity in horizontal exhaust appli-

cation. To be used with boiler exhaust. Diameter range from 6”to 16 “. Material thickness is the same as the vent section it isused with.

STARTING ADAPTER (SA)1. Used to connect the flue to the appliance. It allows flue

gases analysis by means of the verification plug.2. See Fig.E-10 and E-10a for assembly.

ADJUSTABLE LENGTH (AL)1. Used in straight runs of models HEP, HEPL and HEPL2, the

Adjustable Length (AL) serves two major functions:a) To make up for odd lengths of pipe in short runsb)To provide for joint sealing.

2. This part is designed to be adjustable to any needed exactlength. It’s internal joint must be sealed by working sealantunder the seal section, as well as at the joint between themale and the female ends to be closed with the Assembly Band(AB).3. The adjustable length includes a main section and an

outer sliding section that can be secured in the desired lengthposition. Cutting the main section may be required for properfitting.4. The sliding section is designed to fit outside the standard

main section.5. Once the final length of the section is set, it is secured

using a single clamp and screw. This seal section will preventthe inner section from slipping after the assembly.6. The sliding outer jacket is 304 stainless steel of the same

thickness as that used on piping outer casings.7. It is placed around the assembled liner and finishes the

appearance of the Adjustable Length (AL).8. For detailed methods of installation see instructions con-

tained elsewhere in this section.
