These minimum
clearances replace any
other recommended
clearances supplied with
your ANS Z21.11.2
approved gas logs.

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 an equipment
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 16, page 10).
IMPORTANT:
Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.

Mantel Clearances for Built-In
Installation
If placing mantel above built-in fireplace,
you must meet minimum clearance between
mantel shelf and top of fireplace opening.

INSTALLING GAS PIPING TO
FIREPLACE LOCATION
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)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connec-
tor (if allowed by local codes) (not provided)
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
CAUTION: Never connect
heater directly to the propane/LP
supply. This heater requires an ex-
ternal regulator (not supplied). In-
stall the external regulator between
the heater and propane/LP supply.

NOTICE: If your installation does
not meet the minimum clearances
shown, you must do one of the
following:
• raise the mantel to an accept-
able height
• remove the mantel
NOTICE: Surface temperatures of
adjacent walls and mantels be-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch. If
installed properly, these tempera-
tures meet the requirement of the
national product standard. Fol-
low all minimum clearances
shown in this manual.
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional CSA design-certified
equipment shutoff valve from your dealer.
See Accessories, pages 24 and 25.
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, heater 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.
