SECTION TWO – Heater Installation
Heater Venting – Negative Pressure
2. Install the metal Flue Collar in the Vent Body of
the heater (located under the outside vent cover).
Fasten the metal Flue Collar to the Vent Body with
two #10 sheet metal screws. Use UltraCopper
cone RTV to seal the metal Flue Collar to the Vent
Body. Follow instructions supplied with the metal
Flue Collar. Before connecting the metal Flue
Collar to the Vent Body, wet a clean cloth or paper
towel with isopropyl alcohol (rubbing alcohol) and
vigorously wipe the socket of the Vent Body.
Immediately wipe the cleaned surfaces dry with a
clean cloth or paper towel. Repeat for the exterior
of the 4" end of the metal Flue Collar. Attach the
metal Flue Collar to the Vent Body using the RTV
supplied with the kit, following the instructions
included with kit. D D D D o o o o n n n n o o o o t t t t use a draft hood with
this heater.
3. Attach the vent pipe to the Metal Flue Collar with
sheet-metal screws.
Risk of fire or asphyxiation if vent is
not assembled according to manufacturer's instruc-
tions or if vent parts from different manufacturers
are mixed. Vent parts from different manufacturers
ARE NOT interchangeable. Mixing parts from more than
one manufacturer may cause leaks or damage to vent.
When assembling a vent, pick one manufacturer and be
sure that all vent parts come from that manufacturer
and are specified by the manufacturer for your system.
Follow manufacturer's instructions and local and
National Fuel Gas Code requirements carefully during
assembly and installation.
4. Install vent pipe so that it can expand and contract
freely as the temperature changes. Support the vent
pipe according to applicable codes and the vent
sili- manufacturer's instructions. Pipe support must
®
allow the vent pipe free movement out and back,
from side to side, or up and down as necessary,
without putting a strain on the heater or vent body.
Slope horizontal pipe runs up from the heater at
least 1/4"per foot (2 cm/meter). Install Listed con-
densate drains at low points where condensate
might collect. Plumb condensate drains to a drain
through hard piping or high-temperature tubing
such as silicone rubber or EPDM rubber – do not
use vinyl or other low temperature tubing. Follow
drain manufacturer's installation instructions.
5. Use Listed firestops for floor and ceiling penetra-
tions. Use Listed thimble for wall penetrations. Use
a Listed roof flashing, roof jack, or roof thimble for
all roof penetrations. Do not fill the space around
the vent (that is, the clear air space in the thimble
or firestop) with insulation. The roof opening must
be located so that the vent is vertical.
6. See Table 2-F (Page 2-7) for height of vent termina-
tion above the roof (U.S.) and Figure 2-7 (Page 2-7)
for U.S. venting requirements. See Figure 2-8 (Page
2-7) and Standard CSA-B149.1 for Canadian vent-
ing requirements.
7. Do not run the heater vent into a common vent
with any other appliance.
Fire Hazard. Do not vent the heater
directly into a masonry chimney. Installation into a
masonry chimney must use a chimney liner and must
meet National Fuel Gas Code requirements and all
local code requirements.
