MAINTENANCE AND CLEANING
WARNING! If the user of this appliance fails to maintain it in the condition
in which it was shipped from the factory or if the appliance is not
used solely for its intended purpose or if appliance is not maintained
in accordance with the instructions in this manual, then the risk of a
fire and/or the production of carbon monoxide exists which can cause
personal injury, property damage or loss of life.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous furnace
operation.
Always verify proper operation of furnace after servicing.
You, as the owner/user, should inspect the furnace monthly during the
heating season for presence of soot on vent. Operating the furnace
under this condition could lead to serious property damage, personal
injury or loss of life. If soot is observed on the vent, immediately shut
furnace down and contact a qualified service agency.
Listed below are several safety related items that you should follow
during the heating season to assure continued safe operation of the
Furnace.
1.
Inspect furnace venting. Venting must be free of obstructions, void
of soot and properly terminated to the atmosphere. (Refer to Installation
Manual.)
WARNING! Do not install screens over the vent for any reason. Screens
will become restricted and cause unsafe furnace operation. Accessories
are being marketed for RV products which we do not recommend. For your
safety, only factory authorized parts are to be used on your furnace.
2.
Periodically inspect the vent for obstructions or presence of soot.
Soot is formed whenever combustion is incomplete. This is your visual
warning that the furnace is operating in an unsafe manner. If soot is
present, immediately shut furnace down and contact your dealer or a
qualified service person.
3.
Periodically observe the main burner flame to assure it is burning
with a hard blue flame with well defined burner ports (See Figure 2). If
flame appears yellow or burner has a lazy flame, shut furnace down. It
is possible that burner needs cleaning or replaced. To inspect the main
burner, remove the four (4) screws (A, B, C and D) securing the burner
access door to the combustion chamber (See Figure 1). If excessive
rust and corrosion are present on burner surface, the burner must be
thoroughly cleaned or replaced. The burner may be cleaned using a
steel wire brush and blown clean using high compression air. Contact a
qualified service person for assistance.
NOTE:
To observe flame, cabinet front must be removed. Operation of
burner can then be observed through the viewing window on front of
chamber (See Figure 1).
4.
Keep furnace clean. More frequent cleaning may be required due to
excessive lint from carpeting, bedding material, etc. It is imperative that
control compartments, burners and circulating air passageways of the
appliance be kept clean.
5.
The motor is permanently lubricated and requires no oiling.
6.
Keep the furnace area clear of any combustible materials, gasoline
or other flammable vapor and liquids.
7.
Before operating furnace, check the location of the furnace vent to
make sure it will not be blocked by the opening of any door on the trailer.
If it can be blocked, do not operate the furnace with the door open.
8.
Do not restrict the flow of combustion air or the warm air circulation to
the furnace. To do so could cause personal injury and/or death.
9.
Never operate the furnace if you smell gas. Do not assume that
the smell of gas in your RV is normal. Any time you detect the odor of
gas, it is to be considered life threatening and corrected immediately.
Extinguish any open flames including cigarettes and evacuate all
persons from the vehicle. Shut off gas supply at LP gas bottle. (See
safety notice on front cover of this manual.)
10.
Immediately shut furnace down and call a service agency if furnace
cycles erratically or delays on ignition.
WARNING! Should overheating occur, or the gas supply fail to shut off,
shut off the manual gas valve to the appliance before shutting off the
electrical supply.
11.
Never attempt to repair damaged parts. Always have them replaced
by a qualified service agency.
12.
Never attempt to repair the furnace yourself. Seek the help of a
qualified service person.
13.
Never restrict the ducting installed by your trailer manufacturer. To
do so could cause improper furnace operation.
14.
Do not install air boosters in the duct system. Such devices will
cause the furnace to cycle on limit and to have erratic sail switch
operation.
15.
Clothing or other flammable material should not be placed on or
near the appliance.
16.
Always follow the Operating Instructions. Do not deviate from the
step-by-step procedures.
17.
Do not use this appliance if any part has been submerged under
water. Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and any gas
control that has been submerged under water.
18.
When considering add-on rooms, porch or patio, attention must be
given to the venting of your furnace. For your safety, do not terminate
furnace vent inside add-on rooms, screen porch or onto patios. Doing
so will result in products of combustion being vented into the room or
occupied areas.
19.
In any installation in which the vent of this appliance can be covered
due to the construction of the RV or some special feature of the RV
such as slide out, pop-up etc. always insure that the appliance cannot
be operated by setting the thermostat to the positive “OFF” position and
shutting off all electrical and gas supply to the appliance. Never operate
furnace with vent covered.
Your furnace should be inspected by a qualified service agency
yearly before turning the furnace on. Particular attention should
be given to the following items.
1.
Inspect furnace installation and vent termination to be sure furnace
is properly secured in place, that vent terminates to the atmosphere
and that vent tubes overlap properly. (See installation manual supplied
with furnace.)
2.
Inspect chamber and venting to assure that these components
are physically sound, without holes or excessive corrosion and that
the installation and/or reinstallation is in accordance with Suburban’s
Installation Instructions. (Reference installation manual supplied with
furnace.)
WARNING! It is imperative that the products of combustion be properly
vented to atmosphere and that all combustion air supplied to burner be
drawn from outside atmosphere.
3.
Check the base on which furnace is mounted. Be sure it is physically
sound, void of any sagging, deterioration, etc.
4.
Inspect furnace, the venting, ducting and the gas piping to furnace
for obvious signs of deterioration. Correct any defects at once.
5.
Inspect combustion chamber for restrictions in exhaust or intake. It is
imperative that the flow of intake combustion air and the flow of exhaust
gases being expelled to the outside atmosphere not be obstructed. Any
soot or loose debris should be blown out using compressed air. (See
Figure 3.)
6.
Inspect all gaskets. If any gaskets show signs of leakage or
deterioration, replace them. Safe operation of the furnace depends on
all gaskets being tight.
7.
Inspect return air inlet openings to the furnace. Remove any
restrictions to assure adequate air flow.
