LOCATION OF FIREPLACE
Carefully select the best location for installa-
tion of your VF4000 series Unvented Room
Heater. The following factors should be taken
into consideration:
•Clearance to side wall, ceiling, woodwork
and windows.
•Location must not be affected by drafts
causedby kitchen exhaustfans, returnair reg-
isters for forced air furnaces/air conditioners,
windows or doors.
•Installation must provide adequate ventila-
tion and combustion air.
•Donot installthe VF4000series heaters ina
sleeping room or bathroom.
•Neverobstructthefrontopeningoftheheater
or restrict the flow of combustion and ventila-
tion air.
•This appliance may be installed in an after-
market* manufactured (Mobile) Home, where
not prohibited by state or local codes.
*Aftermarket: Completionof sale, not for pur-
pose of resale, from the manufacturer.
•Minimizemodificationstoexistingconstruc-
tion.Referto

To ensure even heat distribution, it is best to
positiontheheatercentrallyagainstthelongest
wall of the room. Make sure there is adequate
ventilation where the heater is installed. The
gas appliance will shut off if the oxygen level
falls below 18%.
Theseappliancesareuniquelysuitedforinstal-
lations requiring a utility shelf positioned di-
rectly above the fireplace. Utility shelves like
these are commonly used for locating televi-
sion sets and decorative plants.
To provide for the lowest possible shelf sur-
face,combustible materialsusedto supporta
utility shelf directly above these appliances
shouldbe positionedjust abovethe appliance
top spacers. The minimum height from the
base of the VF4000 to the underside of com-
bustible materials used to construct a utility
shelf is 37-1/4” (946 mm).
The appliance should be mounted on a fully
supported base extending the full width and
depthoftheunit.Theappliancemaybelocated
on or near conventional construction materi-
als.However,ifinstalledoncombustiblemate-
rials, such as carpeting, vinyl tile, etc., a metal

Example: 2560 ft 3/ 50 ft 3= 51.2
or 51,200 BTU/Hr the space can support.
3.Add the BTU/Hr of all the fuelburning appli-
ances in the space.
