RCH100 Installation and Operation Instructions
rev: 11/15/06

WARNING: Due to the continuous length of time the heater might be in operation, a 100 lb. LP gas
cylinder may not be sufficient in size. Manifolding several cylinders together is a practical way of
increasing the time of operation of these heaters. Operation of the heater with insufficient sized cyl-
inders or when the liquid level becomes too low will result in poor heater performance and can
cause sooting. Consult your LP gas dealer for proper sizing of container.
Always turn the gas off at the tank or cylinder when the heater is not in use. When in operation, keep the heater a safe dis-
tance from the LP gas container and combustible materials as indicated on the heater and in the instructions. Fasten LP
cylinders securely so they cannot be knocked over.
When the heater is to be stored indoors, the connection between the propane supply cylinder(s) and the heater must be dis-
connected and the cylinder(s) removed from the heater and stored in accordance with the Standard for the Storage and
Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 and CSA B149.1, Natural Gas and Propane Installation Code.
7.1. LP models only - Regulator and hose assembly instructions
7.1.1. Attach the POL fitting on the regulator to the LP gas tank / cylinder as shown in Figure 2 ”Regulator and hose
assembly” on page 6. Use a wrench to tighten the connection.
Note:
This fitting has left hand threads (like a gas barbecue and tank). Screw the POL fitting counter-clockwise.
CAUTION: DO NOT try to overtighten this connection. Overtightening may damage the “Excess flow control safety device” in
the POL fitting regulator.
7.1.2. Remove the plastic cap from the end of the 3/8” flare fitting. Connect the 3.8” flare swivel nut on the end of the reg-
ulator/hose assembly to the 3/8” flare tube fitting on the burner assembly, as shown in Figure 2 ”Regulator and
hose assembly” on page 6. Use two wrenches to tighten this connection, screwing the swivel nut clockwise onto the
supported 3/8” flare fitting.
7.1.3. After all the connections are made, they must be checked for leaks prior to operation. The following instructions
describe the leak checking procedure.
i.
Make sure the control knob on the heater is turned to “OFF” prior to opening the valve on the LP tank/cylinder.
ii.
Open the tank/cylinder valve fully (turn tank knob counterclockwise). Apply a rich soap and water solution to the POL
fitting into the tank/cylinder as well as the 3/8” flare swivel fitting at the heater. Bubbles indicate leaks which must be
fixed before the heater is operated.
iii.
Tighten the joints to stop any leaks. Repeat steps i. and ii. after any tightening. If you are unable to stop the leaks, DO
NOT operate the heater. Contact your local LP dealer.
EXPLOSION HAZARD
Failure to do so may result in death,
serious injury or property damage.
WARNING
Regulator must be connected to LP
gas cylinder. Maximum operating
pressure 1/2 PSI or 14 W.C.
High gas pressure will cause an
explosion.
