N. GAS IGNITOR NOT WORKING
1. Gas pressure too low - The pressure inside a propane
tank decreases as the temperature drops, even to
the point of having zero pressure. Larger and/or
fuller tanks can withstand longer periods of colder
temperatures before losing all pressure. Therefore,
smaller, less full tanks will be more susceptible to
cold temperatures. In cold weather, tanks should be
kept full and the tank and hose should be sheltered.
2. Burn chamber obstructed - Clean the burn
chamber, especially at the end of the auger. Make
sure there is no ash or material inside the burn
chamber and that all of the combustion air holes are
open and unobstructed.
3. Aerator combustion air holes obstructed -
Remove aerator and clear deposits from combustion
air holes.
4. Ignitor wire loose - Make sure the connector on the
end of the ignitor is threaded on tightly and that the
ignitor wire has a good connection.
5. Electrode dirty or damaged - Clean the electrode
using a coarse cloth rag. If there is excessive
creosote or deposits on the electrode that are difficult
to remove, oven cleaner may be used to soften the
deposits. Inspect for cracked insulation, damage or
for any loose components.
6. Combustion fan obstructed - Inspect the
combustion fan and remove any obstructions.
7. Air proving switch tubes obstructed or
disconnected - Make sure the fan is operating. The
air tube from the back port (P1) of the air proving
switch connects to the nipple on the bottom of the
fan; the air tube from the front port (P2) of the air
proving switch is installed in the bracket on the
fan. Make sure both tubes are securely connected
to the correct port and are not kinked, cracked or
obstructed.

8. Burn chamber temperature is 300˚F or higher -
If the FireStar controller detects the temperature of
the burn chamber is at or above 300˚F (149˚C), the
gas ignitor will not light. Allow the burn chamber
to cool. To display the temperature of the burn
chamber, press the Water Temp
button. The
LED display will indicate the actual temperature of
the burner up to 999˚F or, if it is higher, as a decimal
representation (e.g., 1500˚F will display as 1.5).
NOTE: If the thermocouple in the burn chamber
becomes damaged or is faulty, the FireStar will
indicate a temperature of 300˚F (149˚C). If the
burn chamber is relatively cool and the FireStar
indicates 300˚F (149˚C), the thermocouple will
need to be replaced. Contact your Central Boiler
dealer.
