FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the fireplace you are installing. If you have conflicting gas types, do not
install fireplace. See dealer where you purchased the fireplace for proper fireplace for your gas
type.
INSTALLING GAS PIPING TO FIREPLACE LOCATION
INSTALLATION ITEMS NEEDED
Before installing, make sure you have the items listed below:
•
External regulator (supplied by installer)
•
Tee Joint
•
Piping (check local codes)
•
Pipe wrench
•
Sealant (resistant to propane/LP gas)
•
Test gauge connection*
•
Sediment trap (optional but recommended)
•
Approved flexible gas line with gas connector (if allowed by
local codes - not provided)
*A CSA design-certified equipment shutoff valve with 1/8”
NPT tap is an acceptable alternative to test gauge connec-
tion. Purchase the CSA design-certified equipment shutoff
valve from your dealer.
For propane/LP connections only, the installer must supply an external regulator. The external
regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between
11 and 13 inches of water. If you do not reduce incoming gas pressure, burner system regulator
damage could occur. Install external regulator with the vent pointing down as shown in Figure 16.
Pointing the vent down protects it from freezing rain or sleet.
W
ARNING
A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.
CAUTION
For propane/LP units, never connect
fireplace directly to the propane/LP
supply. This burner system requires an
external regulator (not supplied). Install
the external regulator between the burn-
er system and propane/LP supply.
CAUTION
Use only new black iron or steel pipe. In-
ternally tinned copper or copper tubing
can be used per National Fuel Code, sec-
tion 2.6.3, providing gas meets hydrogen
sulfide limits, and where permitted by
local codes. Gas piping system must be
sized to provide minimum inlet pressure
(listed on data plate) at the maximum
flow rate (BTU/hr). Undue pressure loss
will occur if the pipe is too small.
W
ARNING
External regulators may be necessary
for natural gas. One- or two-pound sys-
tems will damage this appliance and
may cause fire hazard.
