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 a blocked 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. Iffuse

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 a supply of gas sufficient
to meet the maximum demand of the heater without loss of pressure.

..

2.

A shut off valve (and appliance connector valve) shouldbeinstalledinthe 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 a type which resists the action

of liquefied petroleum gas.

5.

Supplied gas pressure mustbewithin the limits showninthe 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.

8.

A 1/8" test plug is provided for testing of manifold pressure see schematic for location.
At time of installation installer must supply a

1/8 inch N.P.T. plugged tapping, accessible for test

gauge connection of the appliance.
