STOVE AND B-VENT
BURNER SYSTEM
INSTALLATION
INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified in-
staller or service person must
connect burner system to gas
supply. Follow all local codes.
CAUTION: For propane/LP
units, never connect heater di-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
CHECK GAS TYPE
Use proper gas type for the burner system
unit you are installing. If you have conflict-
ing gas types, do not install burner system.
See dealer where you purchased the burner
system for proper system according to your
gas type.
NOTICE: This heater is intended
for use as supplemental heat. Use
this heater along with your pri-
mary heating system. Do not in-
stall this heater as your primary
heat source. If you have a central
heating system, you may run
system’s circulating blower while
using heater. This will help circu-
late the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
TROUBLESHOOTING
VENTING
PROBLEMS
Continued
Negative Pressure in the
Dwelling
An extremely tight house may not supply
adequate combustion and venting air. Use
of mechanical exhaust such as a dryer vent
or range vent may worsen the problem. An
air exchange system must be installed in the
dwelling to correct this problem.
Flue Gas Cooling
Venting exposed to extremely cold tem-
peratures or venting of single wall construc-
tion loses heat needed to maintain draft;
massive masonry chimneys absorb needed
heat. If the flue gases cool excessively, draft
is reduced and spillage may result. Use
proper materials, insulate and protect prop-
erly, reline when necessary.
Down Drafts
In certain wind conditions and in certain
relationships with nearby structures and
objects, high pressure conditions may affect
draft negatively. Relocate the vent cap, raise
its height, or use an approved high wind cap.
Installation Items Needed
Before installing stove and burner system,
make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas con-
nector (if allowed by local codes) (not
provided)
* A CSA/AGA design-certified equipment
shutoff valve with 1/8" NPT tap is an ac-
ceptable alternative to test gauge connec-
tion. Purchase the CSA/AGA design-certi-
fied equipment shutoff valve from your
dealer.
For propane/LP connections only, the in-
staller must supply an external regulator.
The external regulator will reduce incoming
gas pressure. You must reduce incoming
gas pressure to between 11 and 14 inches of
water. If you do not reduce incoming gas
pressure, heater regulator damage could
occur. Install external regulator with the
vent pointing down as shown in Figure 30.
Pointing the vent down protects it from
freezing rain or sleet.
