Installation Instructions and Owner’s Manual
Universal Unvented Room Heater
4. If installing bottom mounting screw into hollow
or solid wall, install wall anchors. Follow steps 1
through 4 under Attaching to Wall using Anchor. If
installing bottom mounting screw into wall stud, drill
holes at marked locations using 9/64” drill bit.
5.
Re-place heater onto mounting bracket.
6. Place spacers between bottom mounting holes and
wall anchor or drilled hole.
7.
Hold spacer in place with one hand. With the other
hand, insert mounting screw through bottom
mounting hole and spacer. Place tip of screw in
opening of wall anchor or drilled hole.
8.
Tighten both screws until heater is firmly secured to
wall. Do not over tighten.
Note: Do not re-place front panel at this time.
Replace front panel after making gas connections and
checking for leaks.
FLOOR MOUNTING AWAY FROM WALL:
Installing Support Feet (See figure 11.)
1. Lay heater onto table on its back with bottom
edge overhanging table edge.
2. Securely attach feet to bottom of heater using 2 –
self-tapping screws each.
Figure 11
Note: Feet should have long end going out the front of
heater, and the edge coinciding with side of heater. If
feet overhang side of the heater, switch leg location.
3. Place heater on non-combustible surface (see
Locating Heater, page 6) before proceeding
with gas connection. If this will be a permanent
location, heater may be locked into position using
anchoring holes in mounting feet.
Note: Use of floor mounting feet will require you to
use a 3/8 NPT street elbow to make gas connection.
DUAL FUEL CAPABILITY
This appliance can be used with propane or natural gas.
The factory has set the heater up for propane operation
by default. If using propane, remove the plug from
the Propane/LP regulator and do not make any further
adjustments. If converting for use with Natural Gas See
“FUEL CONVERSION INSTRUCTIONS” on page 11 before
proceeding.
NATURAL GAS
CAUTION:
Never connect heater to private (non-
utility) gas well. This gas is commonly known as well-
head gas.
IMPORTANT:
Check your gas line pressure before
connecting heater to gas line. Gas line pressure must be
no greater than 10.5 inches of water. If gas line pressure
is higher, heater regulator damage could occur.
PROPANE/LP
CAUTION:
Never connect heater directly to the
Propane supply. This heater requires an external
regulator (not supplied). Install the external regulator
between the heater and Propane/LP supply.
The installer must supply an external regulator.
The external regulator will reduce the 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. Pointing the
vent down protects it from freezing rain or sleet.
CONNECTING TO GAS SUPPLY
CAUTION:
Use only new black iron or steel pipe. Internally-
tinned copper tubing may be used in certain areas. Check
your local codes. Use pipe of large enough diameter to
allow proper gas volume to heater. 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 of
test gauge hookup. NPT tap must be upstream from heater
(see figure 12).
*A CSA/AGA certified equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certified equipment
shutoff valve from your dealer.
IMPORTANT:
Install an 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 threads. This will
prevent excess sealant from going into pipe. Excess sealant
in pipe could result in clogged heater fuel train. Sealant will
also help reduce the chance of cross threading.
CAUTION:
Use pipe joint sealant that is resistant to
Propane/LP and/or Natural Gas depending on fuel used.
WARNING:
A qualified service person must connect
heater to gas supply. Follow all local codes.
WARNING:
This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection to the pressure
regulator. Use of floor mounting feet will require
you to use a 3/8 NPT street elbow to make gas
connection.
CAUTION:
Two gas line installations at the same time
are prohibited. The access plate to the switching means
shall not be opened while the heater is in operation.
