3.9.5 Intake Vent Pipe Materials
Δ Schedule 40 PVC, CPVC or ULC S636 pipe
and ttings and ABS pipe and ttings can be
used for combustion air intake on Glow Brand
products.
Δ Transition cement must be used if ABS pipe is
connected to the PVC appliance adapters.
Δ All plastic components and specied primers
and glues of the certied vent system must be
from a single manufacturer and not intermixed
with other system manufacturers vent system
parts.
Δ The vent for this appliance shall not terminate
over public walkways, near soft vents, crawl
spaces or other areas where condensate or
vapour could create a nuisance or hazard or
cause property damage or where condensate
vapour could cause damage or could be
detrimental to the operation of regulators, relief
valves of other equipment.
Equivalent Lengths
Δ Reduce the maximum vent length accordingly
for each elbow used.
Δ Each 3” 45° elbow equates to 2.5 linear feet of
vent pipe.
Δ Each 3” 90° short radius elbow equates to 7.5
linear feet of vent pipe.
Δ Each 3” 90° long radius elbow equates to 5
linear feet of vent pipe.
Δ The maximum length listed is for exhaust vent
only. The intake length should be equal length.
Δ The total maximum equivalent vent pipe
distance cannot exceed 100ft for horizontal and
vertical venting distance.
Δ The maximum lengths include elbows.
Δ Exceeding the maximum venting distance may
cause the appliance to malfunction or cause an
unsafe condition.
Minimum Vent Lengths
2” Diameter - 6” pipe (Length) plus one elbow.
2 ½” Diameter - 6” pipe (Length) plus one elbow.
3” Diameter - 6” pipe (Length) plus one elbow.
