WARNING!
Do not insulate PVC/CPVC exhaust pipe nor install into an
enclosure, closet, alcove or any other obstruction thereby
preventing the cooling of the exhaust pipe.
Installation must comply with local requirements and with the National Fuel Gas Code, ANSI
Z223.1 for U.S. installations or CSA B149.1 for Canadian installations. For installation in
Canada, vent pipe system must be certified to ULC-S636 (see Table 3-2).
Installation of a stainless steel vent system should adhere to the stainless steel vent
manufacturer’s installation instructions supplied with the vent system.
The installer must use a specific vent starter adapter at the flue collar connection, supplied by
the vent manufacturer to adapt to its vent system. See Table 3-3 for approved vent adapters.
WARNING!
Do not insulate polypropylene exhaust pipes nor install into an
enclosure, closet, alcove or any other obstruction thereby
preventing the cooling of the exhaust pipe.
Do not use water-based lubricants on joints. Never use
hydrocarbons-based lubricants because they would destroy
gaskets.
3.16.5.4 Single Pipe Venting (Unsealed Combustion)
Commercial applications utilizing this heater may be installed with a single pipe carrying the flue
products to the outside while using combustion air from the equipment room. In this case the
following conditions and considerations must be followed:
Utilizing the single pipe method, provisions for combustion and ventilation air must be in
accordance with Air for Combustion and Ventilation, of the latest edition of the National Fuel
Gas Code, ANSI Z223.1, in Canada, the latest edition of CGA Standard B149 Installation Code
for Gas Burning Appliances and Equipment, or applicable provisions of the local building codes.
For installation in Canada, vent pipe system must be certified to ULC-S636 (see Table 3-3).
There will be an increase in the noise level during normal operation from the inlet air opening.
Vent system and terminations must comply with the venting instructions as set forth in Section
3.16.5.
All vent pipes connections must be secured following manufacturer instruction, properly
supported, and the exhaust must be pitched a minimum of a 1/4 inch per foot back to the boiler
(to allow drainage of condensate). Vent pipe system shall be installed in a way to prevent
accumulation of condensate;
Where exhaust fans, clothes dryers, and kitchen ventilation systems interfere with the operation
of appliances, makeup air shall be provided.
