MAINTENANCE:

Always­keep­the­heater­area­clear­and­free­from­
combustible­materials,­gasoline­and­other­flammable­
vapors­and­liquids.
Keep­the­vent­areas­
(slots­in­the­bottom­
and­the­top­at­the­
front­of­heater)­
clear­at­all­times.
Visually­inspect­the­
pilot­flame­and­
burner­periodically­
during­use.­The­
pilot­flame­should­
Figure­5
be­blue­in­color­
(not­yellow)­and­will­extend­beyond­the­thermocouple.­The­
flame­will­surround­the­thermocouple­just­below­the­tip,­
see­Figure­5.
­A­slight­yellow­flame­may­occur­where­the­pilot­flame­
and­main­burner­flame­meet.­The­burner­should­be­bright­
orange­(with­a­slight­blue­color­around­the­border,­a­red-
orange­haze­that­is­visible­on­the­ceramic­tile­is­acceptable)­
and­without­a­noticeable­flame.­A­blue­flame­that­rolls­out­
at­the­top­of­the­ceramic­tile­indicates­an­accumulation­of­
dust,­lint­or­spider­webs­inside­the­casing­assembly­and­
main­burner­assembly.­If­the­pilot­is­yellow­or­the­burner­
has­a­noticeable­flame,­cleaning­may­be­required.­Use­the­
following­procedure­to­inspect­the­casing­assembly­and­
main­burner­assembly.
It­is­necessary­to­periodically­check­the­burner­orifice­and­
burner­venturi­tube­to­make­sure­they­are­clear­of­insects/
nests­or­spider­webs­that­may­accumulate­over­time.­A­
clogged­tube­can­lead­to­a­fire.
1­ Allow­heater­to­thoroughly­cool­before­performing­any­
maintenance.
2­ Remove­disposable­1­lb.­cylinder­from­heater­or­turn­
OFF­gas­supply­at­remote­cylinder­valve,­and­disconnect­
hose­from­heater.
3­ Remove­(4)­four­screws­that­secure­the­rear­cover­to­
the­Heater.
4­ Pivot­cover­outward­from­bottom.­Release­from­2­top­
clips.­Set­aside.
5­ Remove­(4)­four­burner­retaining­screws­and­fuel­line­
from­burner­assembly.­Remove­burner­assembly­from­
back­of­housing.
6­ Inspect­interior­of­casing­assembly­for­accumulation­
of­dust,­lint­or­spider­webs.­If­necessary,­clean­interior­
of­casing­assembly­with­a­vacuum­cleaner­or­apply­air­
pressure.­Do­not­damage­any­components­within­casing­
assembly­when­you­are­cleaning.
7­ Inspect­and­clean­main­burner­orifice­(threaded­into­
orifice­holder).­Orifice­holder­is­attached­to­the­burner­
assembly­venturi­with­(2)­two­screws.
8­ Inspect­and­clean­pilot­(mounted­to­bracket)­by­using­a­

WARNING:­Never­use­needles,­wires,­or­similar­
cylindrical­objects­to­clean­the­pilot­to­avoid­damaging­
the­calibrated­orifice­that­controls­the­gas­flow.
9­ Apply­air­pressure­(max.­30­psi.)­into­ceramic­tile­of­
burner­assembly­and­the­venturi­tube­(ref.­item­#16)­to­
remove­dust,­lint­or­spider­webs.
10­Reassemble­main­burner­orifice­holder­onto­the­burner­
assembly.
11­ Reinstall­burner­assembly­into­the­heater­housing
12­ Reinstall­fuel­line­and­check­for­leaks.
13­ Install­heater­back­cover.
