Page 16

NOTE: Do not use teflon tape on gas line pipe thread. A flexible sealant is recommended.

A minimum of 7" W.C. and a maximum of 14" W.C. upstream pressure under load, and no load conditions must be provided for natural gas or a minimum of 12" W.C. and a maximum of 14" for propane gas.

GAS PRESSURE REGULATOR

The gas pressure regulator is preset at 4" W. C. for natural gas, and 11" W. C. for propane gas. The pressure at the gas valve, taken with a manometer, should be about 3.7" W. C. natural gas (3.9" W.C. for Low NOx) and 10.5" W. C. propane gas. If an adjustment is needed, remove

seal and turn adjustment screw clockwise

to

increase pressure or counter-clockwise

to

decrease pressure.

PLUMBING FOR WATER CONNECTIONS

LOCATION

The RP 2100 heater requires water flow and positive pressure to fire and operate properly. It must therefore be installed downstream of the discharge side of the filter pump. A typical installation is plumbed as follows:

1.The inlet side of the filter is plumbed directly to the discharge side of the filter pump;

2.The outlet side of the filter is then plumbed to the inlet of the heater; and

3.The outlet of the heater is plumbed to the return line to the pool or spa. The pump, filter and heater are thus plumbed in series.
