Maintenance - Dyna-Glo GRAB 'N GO HA10BK User's Manual And Operating Instructions

MAINTENANCE:

Always keep the heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
Keep the vent areas (slots in the bottom and the top at the front
of heater) clear at all times so combustion air and ventilation
is not obstructed. Visually inspect the pilot flame and burner
periodically during use so combustion air and ventilation is not
obstructed. The pilot flame should be blue in color (not yellow)
and will extend beyond the thermocouple. The flame will sur-
round the thermocouple just below the tip, see Figure 5. A slight
yellow flame may occur where the pilot flame and main burner
flame meet. The burner(s) should be bright orange (with a slight
blue color around the border, a red-orange haze that is visible
on the burner is acceptable) and without a noticeable flame. A
blue flame that rolls out at the top indicates an accumulation of
dust, lint or spider webs inside the main burner assembly. If the
pilot is yellow or the burner has a noticeable flame, cleaning
may be required. Use the following procedure to inspect main
burner assembly. It is necessary to periodically check the burn-
er(s) orifice and burner venturi tube to make sure they are clear
of insects/nests or spider webs that may accumulate over time.
It is strongly recommended that these maintenance instructions
be performed annually. A clogged tube can lead to a fire.
1. Allow heater to thoroughly cool before performing
any maintenance.
2. Remove disposable 1 lb. cylinder(s) from heater or turn OFF
gas supply at remote cylinder valve, and disconnect
hose from heater.
3. Remove back panel by removing the top three screws,
lower two rear screws and two screws behind the doors of the
18K.
4. Inspect interior of casing assembly for accumulation
of dust, lint or spider webs. If necessary, clean interior
of casing assembly with a vacuum cleaner or apply air
pressure. Do not damage any components within casing
assembly when you are cleaning.
5. Inspect and clean main burner orifice located at bottom
of burner venturi tube by using a vacuum or apply air
pressure at orifice opening.
6. Inspect and clean pilot (mounted to bracket) by using a
vacuum or apply air pressure through the holes in the pilot
indicated by the arrows in Figure 5.
WARNING: Never use needles, wires, or similar cylindrical
objects to clean the pilot to avoid damaging the calibrated
orifice that controls the gas flow.
7. Apply air pressure into burner assembly to remove
dust, lint or spider webs.
8. Reinstall back panel.
