Installation instructions and Owner’s Manual
run correctly.
IMPORTANT:
Hold pressure regulator with wrench when
connecting it to gas piping and/or fittings.
CHECKING GAS CONNECTIONS
WARNING:
Test all gas piping and connections for
leaks after installing or servicing. Correct all leaks
at once.
WARNING:
Never use an open flame to check for a
gas leak. Apply a mixture of liquid soap and water to
all joints. Bubbles forming show a leak. Correct all
leaks at once.
PRESSURE TESTING GAS SUPPLY PIPING
SYSTEM
Test pressure in Excess of ½ psig (3.5kPa)
1. Disconnect appliance with its appliance main
gas valve (control valve) and equipment shutoff
valve from gas supply piping system. Pres-
sures in excess of ½ psig will damage heater
regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either using
compressed air or opening LP gas valve on
or near the tank.
4. Check all connections and joints in gas supply
piping system. Apply mixture of liquid soap and
water to gas joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Depressurize and relieve pressure in supply
piping system.
7. Reconnect heater and equipment shutoff valve
to gas supply.
8. Reconnected fittings must be checked for leaks
in next section.
Test Pressure Equal To or Less Than ½ psig (3.5 kPa)
1. Close equipment shutoff valve (see figure 13).
2. Pressurize supply piping system by either using
compressed air or opening propane/LP supply
valve.
3. Check all joints from the propane/LP supply
valve to equipment shutoff valve (see figure 14).
Apply mixture of liquid soap and water to gas
joints. Bubbles forming show a leak.
4. Correct all leaks at once.
5. Depressurize and relieve pressure from supply
piping system.
LIGHTING / OPERATING INSTRUCTIONS FOR USE
WITH HOSE CONNECTED TO A REMOTE
CYLINDER, MAXIMUM SIZE 20 LBS:
•
This Heater may be used in a Recreational Enclosure or
Temporary Construction Work Enclosure with a Remote
Refillable Propane Cylinder ONLY when the Cylinder is
Located Outdoors and the Heater is Used with Mr. Heater
Hose assembly supplied.
•
DANGER:
NEVER bring a refillable propane cylinder
indoors. A fire or explosion can occur causing property
damage, serious injury or death!
•
Inspect the hose before each use of the heater. If there is
excessive abrasion or wear, or the hose is cut, replace
prior to using the heater with one of the Mr. Heater Hose
assembly supplied (see parts list).
•
The propane cylinder must include a listed overfilling
protection device as well as a collar to protect the
cylinder valve.
•
Heater must be in an upright position during operation.
•
Make sure five-position Control Knob is in “OFF”
position.
•
Screw hose connector into regulator on heater and screw
connector on other end of hose into a regulated LP-gas
supply cylinder valve. Tighten all hose connections.
•
Open valve at LP-gas supply cylinder.
•
Check all hose connections for leaks with soapy water at
the threaded connection on heater where the hose
connector screws into the regulator and at LP-gas supply
cylinder.
Pressure Testing Heater Gas Connections:
1. Make sure that the heater supply piping system
is connected and has been leak tested as
described above.
2. Make sure control knob of heater is in OFF
position.
3. Open equipment shutoff valve (see figure 13).
4. Open propane/LP supply valve.
5. Check all joints from equipment shutoff valve to
control valve (see figure 14). Apply mixture of
liquid soap and water to gas joints. Bubbles
forming show a leak.
6. Correct all leaks at once.
7. Light heater (see
Operating Your Heater
, pages
8 & 9 for non-thermostat models). Check the
rest of the internal joints for leaks.
8. Turn off heater (see
To Turn OFF Gas to Appli-
ance
, page 10 for non-thermostat models).
9. Replace lower front panel.
