Modine HD 'Hot Dawg'
Vent Pipe Kits
Vent System Accessories
|All pieces below are UL1738
approved for category III venting. The elbows
allow vent the heater at a 45 or 90 degree angle. The drip
tee is required to drain condensation if you do not have a 1/4"
for foot downward slope in your vent line. The GG vent
adapter connects the vent pipe to the heater. Extra vent
pipe is needed if your installation requires more than the 3' of pipe
which is included with the 3" vent system. The adjustable
vent pipes can slide in and out of a fixed vent pipe giving you an
adjustable length. The amount of adjustment available depends on the length of
the pipe it is connected to. NOTE: 2 adjustable vent pipes can't be connected
together. A firestop or thimble is needed
when venting through a combustible wall. It insulates the pipe and provides the
required distance from the pipe to the wall. Firestops can be used with thinner
walls than a thimble which makes them ideal for most greenhouse installations.
The storm collar is needed to seal the air
gap between the pipe and a firestop on the outside wall (Not needed when using
a wall thimble).
What is UL 1738? In short, it is a US standard for gas venting systems
required in category III applications. Category III refers to positive vent pressure
which is created by exhaust blowers in unit heaters. These vent systems must be
constructed of AL29-4CŪ stainless steel, contain silicone gaskets for sealing,
and have a built in mechanical locking band among other requirements.
