Suburban DYNATRAIL NT-30SP Instructions D'installation page 4

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. (See Installing Vent Assembly.)
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 9). 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
(SeeFigure 7). If excessive rust and corrosion are present on burnersurface,
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 7).
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. 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.
