Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time
of ignition.
Flame Failure Device: Activated when burner flame fails. This prevents raw gas from being
released.
Overheat Switch:
Two Fusible
Links:
This device automatically cuts the gas off if the heater exceeds a
predetermined temperature. This
is normally caused by an
obstruction
in front of the louvers, or ablocked fan filter.
Backs up the overheat switch. If the fusible link cuts the unit off, a
service call by an authorized person is required to replace the link.
Overcurrent Prevention Device: This is a 3 amp. glass fuse found on p.e; board. Design
to shut unit down in case of overcurrent. If fuse
bloWs all
indicator lamps will be "OFF".
Power Outage Safety Device: This safety device cuts off gas passage and stops
operation.

1. The gas supply line shall be gas-tight, sized and so installed as to provide asupply of gas sufficient
to meet the maximum demand of the heater without loss of pressure.
..
2. Ashut off valve (and appliance connector valve) should be installed in the upstream of the gas line
to permit servicing.
3. Flexible pipe and any appliance connector valve used for gas piping shall be types approved by
nationally recognized agencies.
4. Any compound used on the threaded joint of the gas piping shall be atype which resists the action
of liquefied petroleum gas.
5. Supplied gas pressure must be within the limits shown in the specifications.
6. After completion of gas pipe connections, all joints including the heater must be checked for gas
tightness by means of leak detector solution, soap and water, or an equivalent nonflammable
solution, as applicable.
CAUTION: Since some leak test solutions, including soap and water, may cause corrosion or stress
cracking, the piping shall be rinsed with water after testing, unless it has been determined that the
leak test solution
is noncorrosive.
7. The appliance and its individual shut off valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressure
in excess of 1/2 psig.
The appliance must be isolated from the gas supply piping system by closing its individual manual
shut off valve during any pressure testing of the gas supply system at test pressures equal to or less
than 1/2 psig.
