CONNECTING TO GAS
SUPPLY
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
CAUTION: Never connect
fireplace directly to the propane/
LP supply. This fireplace re-
quires an external regulator (not
supplied). Install the external
regulator between the fireplace
and propane/LP supply.
The installer must supply an external regu-
lator. 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 incom-
ing gas pressure, fireplace regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
20. Pointing the vent down protects it from
freezing rain or sleet.
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"
or greater diameter to allow
proper gas volume to fireplace. If
pipe is too small, undue loss of
pressure will occur.
CF26PR
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 21).
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.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.

* Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer. See
Accessories, page 28.
** Minimum inlet pressure for purpose of input adjustment.
Install sediment trap in supply line as shown
in Figure 21 . Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into fireplace controls. If sediment
trap is not installed or is installed wrong,
fireplace may not run properly.
