of carbon monoxide poisoning resemble the
u, with headaches, dizziness or nausea. If
you have these signs, the heater may not
be working properly. Get fresh air at once!
Have heater serviced. Some people are
more affected by carbon monoxide than oth-
ers. These include pregnant women, people
with heart or lung disease or anemia, those
under the inuence of alcohol and those at
high altitudes.

propane/LP gases are odorless. An odor-
making agent is added to the gas. The odor
helps you detect a gas leak. However, the
odor added to the gas can fade. Gas may be
present even though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this replace.

for wall and ceiling clearances (see Instal-
lation Clearances, page 5).
2. Everything needed to complete
installation.
3. These models are for outdoor use only.
4. Proper air for combustion and ventilation.

Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in re-
place, you must meet the minimum allowable
clearance between mantel shelf and top of
replace opening shown in Figure 3, page
6. These are the minimum allowable mantel
clearances for a safe installation. Use larger
clearances wherever possible to minimize
the heating of objects and materials placed
on the mantel.

Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• approved exible gas hose and ttings
(supplied with appliance, if allowed by local
codes)
• external regulator (propane/LP models
only)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design-certied equipment
shutoff valve from your dealer.
For propane/LP units, 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 14" of water. If you do not
reduce incoming gas pressure, control valve
damage could occur. Install external regula-
tor with the vent pointing down as shown in
Figure 8. Pointing the vent down protects it
from freezing rain or sleet.

Figure 8 - External Regulator with Vent

REMOTE PROPANE/LP GAS
SUPPLIES AND ENCLOSURES
If appliance is to be permanently connected
to a gas piping system from a remote supply
tank, installation must be in accordance with
local codes or, in absence of local codes, with
the National Fuel Gas Codes ANSI Z223.1/
NFPA 54.
Enclosures may be used to conceal propane/
LP supply tanks and must be constructed to
meet the following minimum construction
requirements:
• An enclosure must have either one open
side or at least four opposing vent open-
ings, top and bottom, which meet minimum
requirements for size and location (see
Figure 9).
• Each opening must provide a minimum or
1/2 inches2 (3,23 cm2) of open area for each
pound propane/LP contained in enclosed
supply tank.
Example: A full enclosure for a 20 pound
propane/LP tank must have at least four,
10 inches2 (65 cm2) openings [a 2" x 5" (5 x
13 cm) square].
• The top openings must be 180° opposing
and be placed at valve level.
• The bottom openings must be 180° op-
posing and be placed 5" (12.7 cm) above
bottom oor.
• There must be 2" (5 cm) minimum clear-
ance from the floor to ground level of
enclosure.

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 log set (see
Figure 10).
IMPORTANT: Install equipment shutoff valve
in an accessible location. The equipment
shutoff valve is for turning on or shutting off
the gas to the appliance.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged heater valves.

We recommend that you install a sediment
trap in supply line as shown in Figure 10.
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and appliance. Locate sediment
trap where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into heater controls. If sediment trap is not
installed or is installed wrong, heater may
not run properly.

1. Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig
will damage control valve.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.

3. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply noncorrosive leak detection
uid to all joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected
ttings for leaks.

Two bags of loose embers are provided with
this unit. For this installation use the embers
that are approximately 1" square in size. If
needed, larger embers can be broken to size.
These embers aid in concealing the burner
pan, directing ames through the ember bed,
quiet operation of the unit and gives a natural
random ame pattern.
Place embers as follows:
1. Place embers around center ember bed
or ember pod.
