or other combustible material other than wood fl ooring, the
fi replace shall be installed on a metal or wood panel extend­ing the full width and depth.

If the optional fan or blower is installed, the junction box
must be electrically connected and grounded in accordance
with local codes. In the absence of local codes, use the cur­rent ANSI/NFPA 70 NATIONAL ELECTRICAL CODE in the
United States.

GENERAL INFORMATION

FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN
TEST-FIRED TO ASSURE ITS OPERATION AND QUAL­ITY! Maximum input is 30,000 BTU/hr for natural gas and

propane. When the fi replace is installed at elevations above
2,000ft, and in the absence of specifi c recommendations
from the local authority having jurisdiction, the certifi ed high
altitude input rating shall be reduced at the rate of 4% for
each additional 1,000ft.

W415-0298 / K / 12.06.07

Suitable for mobile home installation where the mobile
home has been permanently placed on its site. This heat­er must not be installed in a bedroom or bathroom.

This fireplace may be installed in an aftermarket per­manently located, manufactured (mobile) home, where
not prohibited by local codes.

This fireplace is only for use with the type of gas indi­cated on the rating plate. This fireplace is not convertible
for use with other gases, unless a certified kit is used.

Minimum inlet gas supply pressure is 4.5“ water column for
natural gas and 11“ water column for propane. Maximum
inlet gas pressure is 7“ water column for natural gas and
13“ water column for propane. Manifold pressure under fl ow
conditions is 3.5“ water column for natural gas and 10“ water
column for propane.

CARE OF PLATED PARTS

No external electricity (110 volts or 24 volts) is required
for the gas system operation.

Expansion / contraction noises during heating up and cooling
down cycles are normal and are to be expected.

Do not use abrasive cleaners to clean plated parts. Buff lightly
with a clean dry cloth.

This heater is equipped with a pilot light safety
system referred to as an OXYGEN DEPLETION

SENSOR and is designed to turn off the heater

if not enough fresh air is available.

Use only accessories designed for and

listed with your specifi c fi replace.

CARBON MONOXIDE POISONING MAY

LEAD TO DEATH

Early signs of carbon monoxide poisoning resem-

ble the fl u, with headache, dizziness and/or nau­sea. If you have these signs, the heater may not

be working properly. Get fresh air at once! Have

heater serviced.

Some people---pregnant women, persons with heart
or lung disease, anaemia, those under the infl uence
of alcohol, those at high altitudes--- are more af-

fected by carbon monoxide than others.

Ceiling fans or oscillating type fl oor fans can cause fl ame
impingement if directing air at the fi replace. Impinging
fl ames will cause soot or carbon that may enter into living
area. Try reversing ceiling fan or re-directing fl oor fans to
prevent sooting.

COMBUSTION & VENTILATION

AIR PROVISIONS

This heater shall not be installed in a confined space
or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.

In order to avoid the possibility of exposed insulation
or vapour barrier coming in contact with the fireplace
body, it is recommended that the walls of the fireplace
enclosure be ‘finished’, (i.e. drywall/sheetrock) as would
any other outside wall of the home. This will ensure
that clearance to combustibles is maintained within
the cavity.

The National Fuel Gas Code, ANSI Z223.1 defi nes a confi ned
space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m
input rating of all appliances installed in that space and an
unconfi ned 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 a part of the unconfi ned space.

3

per kW) of the aggregate

The CVF36 is rated at 30,000BTUs per hour and
therefore requires a minimum unconfined space
of 1,500 cubic feet.

DETERMINING CONFINED OR UNCON-

FINED SPACE

To determine the volume of the room where the heater is to
be installed, multiply the width x the length x the ceiling height
of that room measured in feet. If any adjoining rooms are con­nected by grills or openings such as kitchen pass-throughs,
etc., the volume of those rooms may be added to the total.

Multiply the room volume by 1000 and divide this amount
by 50 to determine the maximum Btu/hr that the space can
support with adequate combustion and ventilation air.

Add the Btu/hr of all fuel burning appliances located within
the space such as gas furnace, gas water heater, etc. Do not
include direct vent gas appliances which draw their input and
output air from and to the outdoors.

WARNING: If the area in which the heater may be operated
is smaller than that defi ned as an unconfi ned space or if the
building is of unusually tight construction, provide adequate
combustion and ventilation air by one of the methods de­scribed in the National Fuel Gas Code ANSI Z223.1, Section

5.3 or the applicable local code.

ROOM 2

ROOM 1

HEIGHT

LENGTH

Room Volume = Length x Width x Height
Max BTU/hr = Room Volume x 1000 ÷ 50

EXAMPLE 1 EXAMPLE 2

In this example, because there is no door to the adjoining
room, the volume of the adjoining room may be added to the
volume of the room with the heater to get a total unconfi ned

space.

The total unconfi ned space: 800 + 1200 = 2000 cubic feet.

Maximum BTU/h:

If there are no more fuel burning appliances within this space
then the 30,000 BTU/h input of the fi replace is suitable to
be installed. This also assumes that the construction of this
space is not unusually tight.

2000 x 1000

= 40,000 BTU/h

WIDTH

FIGURE 1

If for example,
the length of the rooms is 10 feet,
the width of Room 1 is 10 feet,
the width of Room 2 is 15 feet
the height of the rooms is 8 feet.

The volume of Room 1: 10 x 10 x 8 = 800 cubic feet.

The volume of Room 2: 10 x 15 x 8 = 1200 cubic feet.

If in this example a solid door separates Room 1 from Room
2, the volume of Room 2 could not be used. In this case the
maximum BTU/h would be:

Maximum BTU/h:

This would be considered a confi ned space since it can not
support the 30,000BTU/h input of the heater and it would be
necessary to provide adequate combustion and ventilation
air to Room 1.

800 x 1000

= 16,000 BTU/h

Unusually tight construction is defined as con­struction where:

a) Walls and ceilings exposed to the outside atmosphere
have a continuous water vapour retarder with a rating of
1 perm (6 x 10
gasketed or sealed, and

b) Weather stripping has been added on openable win­dows and doors, and

c) Caulking or sealants are applied to areas such as
joints around window and door frames, between sole plates
and fl oors, between wall-ceiling joints, between wall panels,
at penetrations for plumbing, electrical, and gas lines, and
at other openings.

An unvented room heater is recommended for use as a
secondary heat source rather than as a primary source.
Gas combustion produces water vapour which could occur
at the rate of approximately one ounce of water for every
1,000 BTU/hr of gas input. During the cold weather season,
indoor humidity levels tend to be low. Consequently, this
water vapour can enhance the living space. However if a
problem should occur:

a) ensure suffi cient combustion and circulation air

b) use a dehumidifi er

c) do not use the unvented room heater as a primary

heat source

Without suffi cient fresh air for proper operation, poor fuel
combustion can result. Carbon Monoxide is a result of poor
combustion.

If additional fresh air is required, use one of the meth-
ods described in the National Fuel Gas Code, ANSI Z223.1,
Section 5.3 or the applicable local code.
