24VF Gas Fireplace
Part No. XG0138
Horizon
SAFETY CONSIDERATIONS:
DO NOT START THE FIREPLACE BEFORE READING THIS SECTION:
Any changes made to this heater or the controls may be dangerous and may cause serious injury or death. In the case that changes
were made, warranty will be voided.
• DO NOT use any tools to turn valve. Only use your hand to turn valve.
• DO NOT try to fix anything yourself. Call a certified gas technician. Any attempt to repair may result in a fire or explosion and will void warranty.
• DO NOT operate this heater if any part has been under water.
• DO NOT use this heater for burning trash or cooking.
WARNING:
Improper installation, adjustment, alteration, service or maintenance can cause injury,
property damage, or loss of life. Refer to this manual. Installation and service must be
performed by a qualified installer, certified gas technician, or the gas supplier.
CAUTION: READ THIS SECTION CAREFULLY
FOR FUTURE REFERENCES
Open a window an inch or two for fresh air when us
-
ing this heater.
WARNING: When used without fresh air circulation
the heater may produce carbon monoxide: an odour
-
less poisonous gas.
This heater shall not be installed in a confined space unless provisions are
provided for adequate combustion and ventilation air. The National Fuel Gas
Code defines a confined space as a space whose volume is less than 50
cubic feet per 1,000 BTU per hour (4.8 m3 per KW) of the aggregate input
rating of all appliances installed in that space and an unconfined space as
a space whose volume is not less than 50 cubic feet per 1,000 BTU per
hour (4.8 m3 per kW) of the aggregate input rating of all appliances installed
in that space. Rooms communicating directly with the space, in which the
appliances are installed, through openings not furnished with doors, are
considered part of the unconfined space.
That is to say, add up the BTU of all gas appliances in the room and then
compare to room’s size so as to accept 1000 BTU for each 50 cubic feet
of area. Calculate the total cubic feet of the room derived by the product of
(length x width x height). For example, a room with 8 foot ceilings with 10
foot by 15 foot area has a cubic volume of 1200 cubic feet (8x10x15). Divide
this cubic volume by 50 cubic feet/ 1000 BTU and the result (1200/50) of 24
represents the accumulated BTU capacity in thousands for this room size.
If the result is greater than the accumulated BTU of all the appliances in
the room then the room is an unconfined space and qualifies for unvented
heater installation. If the result is less than the accumulated BTU of all the
appliances in the room then the room is a confined space and the unvented
heater should not be installed in such a small room.
This heater shall not be installed in a room with unusually tight construction
as defined as follows:
• Walls and ceilings exposed to the outside atmosphere have a continu
-
ous water vapour retarder with a rating of 1 perm or openings gasketed or
sealed, and
• Weather stripping has been added on operable windows and doors, and
• Caulking and sealants are applied to areas such as joints around window
and door frames, between sole plates and floors, between wall-ceiling joints,
between wall panels, at penetrations for plumbing, electrical, and gas lines,
and at other openings.
WARNING: If the area in which the heater may be operating is smaller than
that defined as an unconfined space, provide adequate combustion and
ventilation air by one of the methods described in the National Fuel Gas Code
or as described by local codes.
DO NOT use a blower insert, heat exchanger insert or other accessory not
approved for use with this heater.
This fireplace is equipped with a pilot light safety sensor O.D.S. (Oxygen
Depletion Sensor) designed to shut off the heater if there is not enough fresh
air available. DO NOT relight the pilot until you provide fresh air from the
outside. To relight turn the control valve to the lowest level of BTU (6,000). If
the stove still does not light, have it serviced.
DO NOT use this appliance if any part has been under water. Immediately call
a qualified service technician to inspect the heater and to replace any part of
the control system and any gas control which has been under water.
WARNING: DO NOT TAMPER WITH PILOT LIGHT
SAFETY SYSTEM!
Carbon monoxide poisoning may lead to
death.
Early signs of carbon monoxide poisoning resemble the flu with headache,
dizziness, and/or nausea. If you have these signs the heater may not be work
-
ing properly. GET FRESH AIR AT ONCE! Then have the heater serviced.
Some people-pregnant women, people with heart or lung disease, anemia,
those under the influence of alcohol, or those at high altitudes are more af
-
fected by carbon monoxide than others.
CAUTION: When burning, the exterior of the fireplace
may have a high surface temperature. Keep children
out of the fireplace area to avoid burns or clothing ig
-
nition. Young children should be carefully supervised
when they are in the same room with the appliance.
For your safety, before lighting the fireplace, read all safety information in this
manual.
