Natural gas:

resume with chapter 6.4.1

When propane gas is desired, the boiler can be converted to propane gas by means
of a conversion kit. Rinnai Part number:
E50CR:

E75CR:

804000015

E110CR: 804000016

Propane gas:

resume with chapter 6.4.2

When natural gas is desired, the boiler (not for E50CRN) can be converted to natural
gas by means of a conversion kit. Rinnai Part number:
E75CR:

804000023

E110CR: 804000024

6.4.1

Gas connection with natural gas

The gas supply connection must comply with local regulations or, if such
regulations do not exist, with the National Fuel Gas Code, ANSI Z 223.1.

Pipe sizing for natural gas

Contact gas supplier to size the gas supply line and meter.

Gas piping

A sediment trap must be installed upstream of the boiler.

The boiler gas pipe is equipped with external 3/4" M-NPT thread. Use appropriate
sealing.

The connection to the boiler must include a suitable method of disconnection and a gas
control valve must be installed adjacent to the boiler for isolation purposes. The nominal
inlet gas pressure measured at the boiler should be 7" W.C. (18 mbar) for Natural gas
(Gas A). Maximum pressure with no ﬂ ow (lockup) or with the boiler running is 10.5
inches W.C. Minimum pressure with the gas ﬂ owing (verify during boiler startup) is
3.0 inches W.C.

The gas pipe must be properly supported and connected to the boiler.

Make sure that the gas pipe system does not contain dirt, particularly with new
pipes.

Always check the safety of the gas pipe system by means of a bubble test using
leak-search spray.

The boiler must be isolated from the gas supply piping system by closing its
individual manual shutoﬀ valve during any pressure testing of the gas supply
piping system at test pressures equal to or greater than 1/2 PSI (3.5 kPa).
