1.
In the United States, vent system installation must be
in accordance with the latest edition of ANSI Z223.1
(NFPA 54) National Fuel Gas Code. In Canada,
installation must be in accordance with CSA-B149.1
“Installation Code for Natural Gas Burning Appliances
and Equipment” and CSA-B149.2 “Installation Code
for Propane Burning Appliances and Equipment.”

2. A Breidert Type L or Fields Starkap, furnished by the
customer, must be installed at the termination point of
the vent system. See

3. Each duct furnace MUST have its own vent system. It
MUST NOT be connected to other vent systems or to a
chimney.

4. Use UL 1738 listed single wall pipe for the vent system.
For installations in Canada, use UL S636 listed vent
pipe conforming with local building codes, or in the
absence of local building codes, with current
CSA-B149.1 “Installation Codes for Natural Gas
Burning Appliances and Equipment” or CSA-B149.2,
“Installation Codes for Propane Gas Burning
Appliances and Equipment.”

5. Any run of single wall vent pipe passing through an
unheated space must be insulated with an insulation
suitable to 550°F (288°C).

6. The vent system must be installed to prevent collection
of condensate. Pitch horizontal pipes downward
1/4 inch per foot (21 mm/m) towards the vent cap to
facilitate drainage. Vertical vent pipes should be piped
as depicted in

The equivalent length of the vent system must not be
less than 5 feet (1.5 m) and must not exceed 50 feet
(15.2 m). Equivalent length equals the total length of
straight pipe plus 10 feet (3.05 m) for each 90° elbow
and 4 feet (1.22 m) for each 45° elbow.

and 4 feet (1.22 m) for each 45° elbow.
8. For horizontal combustion air systems longer than
5 feet (1.5 m), the system must be supported from
overheard building structures at 4 feet (1.22 m)
maximum intervals in the United States and at 3 feet
(1 m) maximum intervals in Canada.

9. The exhaust vent system must remain at a minimum
distance of 6 inches (152 mm) from all combustible
materials. Any part of the vent system that passes
through a combustible material must be properly
insulated.

For a VERTICAL vent pipe section that passes through a
floor or roof, an opening 4 inches (102 mm) greater in
diameter is required. The opening must be insulated and
flashed in accordance with applicable installation codes.

WARNING
Carbon Monoxide Poisoning!
Never operate separated combustion duct furnaces
without combustion air and flue gas piping in place.
Each duct furnace MUST have its own combustion air
system and MUST NOT be connected to other vent
systems or to a chimney. Your venting system must not
be blocked by any snow, snow drifts, or any foreign
matter. Inspect your venting system to ensure adequate
ventilation exists at all times! Failure to follow these
instructions could result in Carbon Monoxide Poisoning
(symptoms include grogginess, lethargy, inappropriate
tiredness, or flu-like symptoms) which could result in
death or serious injury.
