Install such that gas ignition system components are

protected from water (dripping, spraying, rain, etc.)

during appliance operation and service, (circulator

replacement, condensate trap, control replacement,

etc.).

Locate boiler on level, solid base as near chimney as

possible and centrally located with respect to heat

distribution system as practical.

Verify you have the right size boiler before starting

installation. See rating and capacity table.

When installed in utility room, door should be wide

enough to allow largest boiler part to enter, or to

permit replacement of another appliance such as water

heater.

Boiler installed in building under construction, take

care to insure clean combustion air supply during

construction process. Airborne particulates such as

Install discharge piping from safety relief valve. See

Figure 2.

• Use ¾” or larger pipe.

• Use pipe suitable for temperatures of 375°F (191°C)

or greater.

• Individual boiler discharge piping shall be independent

of other discharge piping.

• Size and arrange discharge piping to avoid reducing

safety relief valve relieving capacity below minimum

relief valve capacity stated on rating plate.

• Run pipe as short and straight as possible to location

protecting user from scalding and properly drain

piping.

• Install union, if used, close to safety relief valve outlet.

• Install elbow(s), if used, close to safety relief valve

outlet and downstream of union (if used).

• Terminate pipe with plain end (not threaded).

WARNING

Burn and scald hazard! Safety relief valve shall be

installed with spindle in upright position only,

following ASME BPV code. Failure to follow these

instructions could result in death or serious injury.

WARNING

Burn and scald hazard. Safety relief valve could

discharge steam or hot water during operation.

Install discharge piping per these instructions. Failure
