DIRECT-VENT PROPANE/LP GAS HEATER

DYNAVENT

®

6.

This furnace must have fresh air for proper
operation. If not, poor fuel combustion and
improper venting of flue gases will result.
Carbon monoxide poisoning from backed-
up flue gases could occur. The State of
California lists carbon monoxide as a re-
productive toxin under Proposition 65.

7.

Never install the furnace
• in a recreational vehicle
• in an alcove
• on an inside wall
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
• behind a door or where an open door

would block normal air flow

8.

Provide the following minimum fur-
nace clearances from furnace front
cover to combustibles (as viewed from
the front of furnace): Below Front
Cover: 6 inches; Adjoining Wall:
12 inches; Above Front Cover:
12 inches; Front: 8 feet

9.

Do not obstruct the flow of combus-
tion and ventilation air in any way. Pro-
vide adequate clearances around air
openings into the combustion chamber
along with adequate accessibility clear-
ance for servicing and proper operation.

10. Provide the following minimum furnace

clearances from furnace cabinet (portion
of cabinet extending into outside air, as
viewed from the rear of furnace):
Cabinet Back: 36 inches
Cabinet Sides: 6 inches
Cabinet Bottom: Must be high enough
off the ground to prevent snow, water,
leaves, or any other objects from block-
ing cabinet vents.

11. Always follow lighting instructions.

Never attempt to light burner with a
match or butane torch.

12. Do not run furnace

• where flammable liquids or vapors

are used or stored

• under dusty conditions

15. Do not use furnace as a cooking device.
16. Do not alter furnace or its controls. Any

change may create a safety hazard.

19. Do not use furnace if any part has been

under water. Immediately call a quali-
fied service person to inspect the fur-
nace and to replace any part of the con-
trol system and any gas control which
has been under water.

Carbon Monoxide Poisoning:

 Early signs

of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, and/or nau-
sea. If you have these signs, the furnace may
not be working properly. Get fresh air at
once!
 Have furnace serviced. Some people
are more affected by carbon monoxide than
others. These include pregnant women,
people with heart or lung disease or anemia,
those under the influence of alcohol, and
those at high altitudes.

Propane/LP Gas:

 Propane/LP gas is odor-

less. An odor-making agent is added to pro-
pane/LP gas. The odor helps you detect a
propane/LP gas leak. However, the odor added
to propane/LP gas can fade. Propane/LP gas
may be present even though no odor exists.

Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this furnace.

1.

A qualified service person must install
furnace.

2.

This appliance is only for use with the
type of gas indicated on the rating plate.
This appliance is not convertible for use
with other gases.

3.

Use only propane/LP gas. Do not con-
vert furnace to use different fuel type.

4.

If you smell gas
• Shut off gas supply.
• Do not try to light any appliance.
• Do not touch any electrical switch; do

not use any phone in your building.

• Immediately call your gas supplier

from a neighbor’s phone. Follow the
gas supplier’s instructions.

• If you cannot reach your gas supplier,

call the fire department.

5.

Do not block the flow of combustion
air (outside air) or heated air (room air)
to the furnace.

fore operating furnace.

You must keep control compart-
ments, burners, and circulating
