B-VENT FREESTANDING FIREPLACE

CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of 1/2"
diameter or greater to allow
proper gas volume to fireplace. If
pipe is too small, undue loss of
pressure will occur.
Installation must include a manual shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
fireplace (see Figure 26, page 13).
Check your building codes for any special
requirements for locating manual shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
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 25.
Pointing the vent down protects it from
freezing rain or sleet.

Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
external regulator (supplied by installer)
piping (check local codes)
sealant (resistant to propane/LP gas)
manual 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)
* An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the A.G.A. design-certified manual
shutoff valve from your dealer.
WARNING: A qualified ser-
vice person must connect fire-
place 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.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.

Install sediment trap/drip leg in supply line
as shown in Figure 26, page 13. Locate
sediment trap/drip leg where it is within
reach for cleaning. Locate sediment trap/
drip leg where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into fireplace gas controls. If sediment trap/
drip leg is not installed or is installed wrong,
fireplace may not run properly.
CHECK GAS TYPE
Use proper gas type for the fireplace unit
you are installing. If you have conflicting
gas types, do not install fireplace. See dealer
where you purchased the fireplace for proper
fireplace 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
systems 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.
