VENTING

INSTALLATION STANDARDS

MATERIAL

UNITED STATES

CANADA

Stainless Steel

UL 1738

Venting must be ULC-S636 certified for use as

PVC, sch 40

ANSI/ASTM D1785

venting material. The venting material must be chosen

CPVC, sch 40

ANSI/ASTM F441

based upon the intended application of the boiler.

Polypropylene

UL1738 or ULC-S636

The flue temperature of the FT changes dramatically

with changes in operating water temperature.

Therefore, it is necessary to assess the application

of the boiler to determine the required certified vent

class. If the FT is installed in an application where

the ambient temperature is elevated, and/or installed

in a closet/alcove, CPVC, polypropylene, or stainless

steel material is required. If the system temperatures

are unknown at the time of installation, stainless,

polypropylene or CPVC material is recommended.

The FT is a Category IV appliance and may be installed

with PVC, CPVC or polypropylene that complies with

ULC

-S636, ANSI/ASTM D1785 F441 (see

Table 3)

a stainless steel venting system that complies with UL
1738 Standard and ULC S636.

Failure to use the appropriate vent material, installation

techniques, glues/sealants could lead to vent failure

causing property damage, personal injury or death.

All venting must be installed according to this manual

and any other applicable local codes, including but not

limited to, ANSI Z224.1/NFPA 54, CAN/CSA B149.1

and ULC-S636. Failure to follow this manual and ap

plicable codes may lead to property damage, severe

injury, or death.

INSTALLATIONS IN CANADA

require the use

of venting material certified to ULCS636. All Gas

vents connected to the FT, plastic, stainless

steel or otherwise must be certified to this ULC

standard. Appropriate selection of vent material is

very important for proper performance and safe

operation of the FT.
The flue temperature of the FT changes

dramatically with changes in operating water

temperature. Therefore, it is necessary to assess

the application of the boiler to determine the

required certified vent class. If the FT is installed in

an application where the outlet water temperature

exceeds 145°F, and/or installed in a closet, class

IIB or higher vent material is required. If the

system temperatures are unknown at the time of

installation, class IIB or higher venting material is

recommended.
IN CANADA

all venting used must meet the

following requirements:
1. ULC-S636 certified and marked
2. The first 3 feet of venting must be accessible

for visual inspection.

NOTICE

DO NOT COMMON VENT FT UNITS. FT units are

never permitted to share a vent with

Category I appliances.

AVIS

NE PAS ÉVENT COMMUNE FT UNITÉS. FT

unités ne sont jamais autorisés à partager un

évent Catégorie I avec les appareils.

NOTICE

For Cascading Installations, please refer to

document 1349 ‘Cascading the FT Series Boiler’,

available online.

4.4 Venting, Exhaust

WARNING

Use of cellular core PVC (ASTM F891), cellular core

CPVC, or Radel® (polyphenolsulfone) used in non-

metallic venting systems is prohibited.

Non-metallic vent pipe (PVC, CPVC, polypropylene

or other) shall NOT be insulated or covered. Insulat

ing or covering non-metallic venting may cause over-

heating which diminishes the integrity of the pipe.
