44 Rinnai M - Series Condensing Boiler Combi Manual
4. Before placing the appliance in operation,
all joints including the connection to the
boiler must be checked for gas tightness by
means of soap, gas leak detector solution,
or an equivalent nonflammable solution, as
applicable. 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 non - corrosive.
5. Use approved and appropriately sized
connectors to connect the boiler to the gas
line. Purge the gas line of any debris before
connection to the boiler.
6. Any compound used on the threaded joint
of the gas piping shall be a type that resists
the action of liquefied petroleum gas
(propane/LPG).
7. 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 and all other gas consuming
appliances at the location without loss of
pressure. If in doubt about the size of the
gas line, refer to section
“ 6.3 Gas Pipe Sizing
Reference Tables. ”
8. Perform a leak and pressure test prior to
operating the boiler. If a leak is detected, do
not operate the boiler until the leak is
repaired.
Gas connection 3/4 in. MNPT connection
Gas Fitting Connection
1. If the system requires a 3/4 in. connection,
attach the 1/2 in. FNPT x 3/4 in. MNPT
connection fitting to the gas fitting on the
bottom of the boiler.
2. Check the type of gas and gas supply
pressure before connecting the boiler. If
the boiler is not of the gas type that the
building is supplied with, converting the gas
type of the boiler is necessary. A gas
conversion kit is included with the boiler.
Refer to section
“ 14.5 Gas Conversion ” in
the Appendix for gas conversion
instructions.
3. Check gas supply pressure at the inlet test
port on the gas valve (see figure). Supplied
gas pressure must be within the limits
shown in section
“3.4 Specifications ” with
all gas appliances operating.
