WARNING
WHILE CARBON MONOXIDE DETECTORS DO PROVIDE ADDITIONAL PROTECTION,
CURRENT LIMITATIONS TO THEIR EFFECTIVENESS REQUIRES THAT YOU
OTHERWISE CONTINUE TO FOLLOW APPROPRIATE INSTRUCTIONS LOCATED IN THE
“INSTALLATION & OPERATING INSTRUCTIONS” AND “USERS INFORMATION”
MANUALS RELATING TO PROTECTING PERSONS FROM THE RISKS OF CARBON
MONOXIDE. REVIEW EACH CO MANUFACTURERS’ EXPLANATION OF THEIR UNIT’S
CAPABILITIES AND FOLLOW THOSE INSTALLATION AND OPERATING MANUAL WHEN
INSTALLING AND OPERATING THESE UNITS.
WARNING
THE CIRCULATING AIR DUCTS MUST BE COMPLETELY AND POSITIVELY SEALED TO
PREVENT COMBUSTION PRODUCTS, INCLUDING CARBON MONOXIDE, FROM
ENTERING THE AIR STREAM.
WARNING
TO ENSURE PROPER INSTALLATION AND OPERATION OF THIS PRODUCT,
COMPLETELY READ AND UNDERSTAND THESE INSTRUCTIONS PRIOR TO
ATTEMPTING TO ASSEMBLE, INSTALL, MAINTAIN, OR REPAIR.
IF THESE INSTRUCTIONS ARE NOT FOLLOWED PRECISELY THERE EXISTS A
POTENTIAL FOR CARBON MONOXIDE POISONING, WHICH CAN RESULT IN SERIOUS
ILLNESS OR DEATH.
WARNING
DO NOT INSTALL A LIQUID PETROLEUM GAS BURNING APPLIANCE IN A PIT,
BASEMENT OR SIMILAR LOCATION WHERE L.P., A HEAVIER THAN AIR GAS, CAN
COLLECT IN LOW AREAS AND MAY NOT DISPERSE NATURALLY. UNLESS ALLOWED BY
LOCAL CODE, APPLIANCES SO FUELED SHALL NOT BE INSTALLED IN AN ABOVE
GRADE UNDER FLOOR SPACE OR BASEMENT UNLESS SUCH LOCATION IS PROVIDED
WITH APPROVED MEANS FOR REMOVAL OF UNBURNED GAS.
These Installation and Operating Instructions are intended for use by fully qualified installation
technicians. This appliance must be installed, adjusted, converted and/or repaired by a quali-
fied installer.
LOCATION
DO NOT install this heater in a mobile home. This heater is designed only for installation in
buildings constructed on site and must be connected to distribution ductwork.
When installed in a utility room or closet, the door opening must be wide enough to allow the
largest part of the heater to enter, or to permit the replacement of another appliance, such as a
water heater.
This appliance is designed to be installed indoors only. DO NOT install outdoors. This appli-
ance should be installed in such a manner so that it is protected from water. If any components
should become submerged, replace the affected parts. After replacing those parts, recommis-
sion the appliance to ensure proper operation. DO NOT use as a construction heater.
DO NOT install in a room used or designed to be used as a bedroom, bathroom or closet, or in
any enclosed space with access only through such a room or space.

7
The heater and it’s individual shut-off must be disconnected from the gas supply piping system
during any pressure testing of that system at test pressures in excess of 50 mbar.
The heater must be isolated from the gas supply piping system by closing it’s individual man-
ual shut-off valve during any pressure testing of the gas supply piping system at pressures
equal to or less than 50mBAR.
If this heater is installed in conjunction with an air conditioning coil, the coil must be down-
stream of the heat exchanger.
A gas-fired heater for installation in a residential garage must be installed in a definite purpose
sealed enclosure with all air for combustion and ventilation originating outdoors.
When installed in a commercial garage the ignition source must be above the level where pet-
rol vapors or any other flammable vapors may accumulate. The circulating ductwork must be
above the level where recirculation of vapors may occur. The heater must be protected from
damage, especially from vehicles.
WARNING
COMBUSTIBLE MATERIAL MUST NOT BE PLACED ON OR AGAINST THE HEATER
CASING. THE AREA AROUND THE HEATER MUST BE KEPT FREE OF ALL
COMBUSTIBLE MATERIAL INCLUDING PETROL AND OTHER FLAMMABLE VAPORS AND
LIQUIDS. THE HEATER ROOM MUST NOT BE USED AS A BROOM CLOSET OR FOR ANY
OTHER STORAGE PURPOSE.
WARNING
THIS HEATER IS EQUIPPED WITH A SOLID BASE PLATE. IT MUST BE LEFT IN PLACE
WHEN USING SIDE RETURN DUCTS. FAILURE TO LEAVE THIS BASE PLATE INSTALLED
COULD CAUSE PRODUCTS OF COMBUSTION, INCLUDING CARBON MONOXIDE, TO BE
CIRCULATED INTO THE LIVING SPACE. THIS CAN CREATE A POTENTIALLY
HAZARDOUS CONDITION, INCLUDING CARBON MONOXIDE POISONING. REFER TO
THE SECTION ON “CIRCULATING AIR SUPPLY” FOR RETURN DUCT INSTRUCTIONS.
VENTING
WARNING
THE VENT MUST TERMINATE OUTDOORS.
ANNUAL inspections of the heater and its vent system is strongly recommended. There should
be no separation, corrosion, or perforation. It is also the contractor’s responsibility to inform the
user of this importance of the results of this inspection.
PROPER INSTALLATION OF THE VENTING SYSTEM IS CRITICAL TO SAFE OPERATION
OF THIS APPLIANCE. CAREFULLY READ AND UNDERSTAND THE INSTRUCTIONS IN
THIS SECTION.
CAUTION
Due to the possibility of CO poisoning -
This appliance SHALL NOT be connected to a vent servicing a solid fuel fireplace.
This appliance SHALL NOT be connected to a flue serving a factory built fireplace.
This appliance SHALL NOT be connected to an unlined masonry chimney.

8
THE USE OF NON-METALLIC FACTORY VENT MATERIAL IS PROHIBITED.
This appliance CAN NOT BE HORIZONTALLY VENTED unless using an optional power
venter such as the SVB-80-5, if permitted by local code.
A vent adapter must be installed between the vent connection on the heater and the field in-
stalled vent system.
Accessories, which improve efficiency, such as flue dampers, shall be removed and discarded
before installing this appliance.
Before installing this heater, inspect existing vent system for separation, corrosion or obstruc-
tions. Repair or replace questionable parts when deemed necessary.
Twin-walled vent pipe is recommended whenever possible, especially when passing through
unheated areas.
Three corrosion resistant screws should be used to secure all joints.
Horizontal runs must incline 20mm per meter from the heater.
Horizontal runs can not be more than 75 percent of the vertical runs.
Support horizontal runs at least every meter to prevent sags and at every elbow.
Atmospherically vented appliances must enter the vent system downstream of the power-
vented appliance. There should be at least a 100mm separation between these entries. The
vent of a lower input appliance must enter the vent above the higher capacity appliance.
The vent terminal must be located not less than 600mm from any operable window or door, air
vent or any ventilation opening, or fresh air intake.
CONSULT LOCAL CODES FOR SPECIAL ADDITIONAL REQUIREMENTS.
SETTING THE GAS PRESSURE
The supply pressure must be adjusted for the type of gas being utilized. This adjustment is
usually completed by the supplying utility.
To adjust the manifold and service pressure use the following method
1) Shut off the manual valve located in the service pressure piping
2) Open the pressure taps located on the combination gas valve & install a manometer on
each pressure tap
3) Restore the supply gas
4) Ignite the unit and allow for 5 mins. Running time
5) Check the pressures and adjust, if necessary. The supply pressure should be adjusted
with all gas fired equipment in the running condition
6) Should the manifold pressure need adjustment – remove the gas valve regulator cover,
turn the adjusting screw clockwise to increase pressure and anti clockwise to reduce the
pressure
7) Shut off the main gas, remove the manometers, close the pressure taps & replace the
gas valve regulator cover
8) Restore the main gas
