Weil-McLain 88 Water and steam boilers — Series 2 —

for Gas, Light Oil, & Gas/Light Oil-Fired Burners

Part No. 550-100-068/1009

Installation must comply with —

State, provincial and local plumbing, heating and electrical

codes.
Regulations of servicing utilities.

ASME Section IV, Low Pressure Boiler and Pressure Vessel Code.

National Fuel Gas Code, ANSI/NFPA 54, when applicable.

National codes where applicable.

Before selecting boiler location

Check for nearby connections to:

Fuel supply.

Electrical power.

System water or steam piping.

Venting systems - see

d. page

29.

Combustion and ventilation air supply — see

e. page

Check area around boiler. Remove any combustible materials,

gasoline and other ﬂammable vapors and liquids.

Failure to keep boiler area clear and free of combustible

materials, gasoline and other ﬂammable liquids and
vapors can result in severe personal injury, death and
substantial property damage.

Provide clearance around boiler

Provide minimum clearances to combustible materials:

"OILERTOP

— 24 inches.

"OILERFRONT

— 48 inches.

"OILERmUE

— 9 inches.

"OILERREAR

— 9 inches.

"OILERSIDES

— 6 inches.

3INGLEWALLVENTPIPE

– 18 inches.

$OUBLEWALLVENTPIPE

– refer to vent pipe manufacturer's

recommendations for vent pipe clearances.

Boiler may be installed on combustible ﬂooring.

See

page 36 for boiler dimensions.

Flue pipe/breeching clearances take precedence over

jacket clearances.

Provide minimum clearances for servicing:

,EFT SIDE

— for cleaning and tankless heater removal –

39 inches.

2EAR

— for breeching — 36 inches.

Allow sufﬁcient space on remaining sides for cleaning, servicing

and burner installation. See burner literature for length and
recommended service clearances.

Lay a foundation, if needed

Floor construction and condition must be suitable for weight of

boiler when ﬁlled with water. See page 35 for approximate boiler
operating weight.
A level concrete or brick foundation, constructed per

2. Figure

and

Figure 2 is required when:

A ﬂoor could possibly become ﬂooded.

Non-level conditions exist.

Before installing boiler

Boiler foundation, when required
