LOCATING THE BOILER

Locating the Boiler

Select level location as centralized with piping system,

and as near chimney as possible.

Place crated boiler at selected location. Remove all

crate material. Please recycle responsibly.

WARNING

Fire hazard. Do not install boiler on combustible

ﬂooring or carpeting. Failure to follow these

instructions could result in death or serious injury.

Do not install boiler on carpeting. For installation

on non-combustible ﬂoors only. For installation on

combustible ﬂooring, special base must be used. (See

Replacement Parts Manual.)

Use metal shims under boiler base legs for ﬁnal leveling

if needed.

Install boiler in location that permits satisfactory

combustion of gas, proper venting, and maintenance

of ambient temperature at safe limits under normal

conditions of use. Boiler location should not interfere

with proper circulation of air. Introduce outside air

if normal inﬁltration does not provide necessary

air.“Fresh Air for Combustion” on page 12.

Notify owner to keep air passages free of obstruction.

WARNING

Burn or Scald Hazard. Discharge line shall be installed to relief valve outlet connection to avoid burns,

scalding, or water damage due to discharge of steam and/or hot water during operation.

Discharge line shall:

• Connect to safety valve outlet. Piped down to safe point of disposal. Check local codes for maximum

distance from ﬂoor or allowable safe point of discharge.

• Pipe size be of equal to or greater than of safety valve outlet over entire length of discharge line.

• Have no intervening shutoff valve between safety valve and discharge to atmosphere. Do not plug or

place any obstruction in discharge line.

• Terminate freely to atmosphere where any discharge will be clearly visible and at no risk of freezing.

• Allow complete drainage of valve and discharge line.

• Install safety valve with spindle in vertical position.

• Do not install shutoff valve between boiler and safety valve.

• Support safety valve discharge piping.

• Be short and straight as possible.

HYDRONIC PIPING

Consider near boiler piping as part of the boiler for proper

water level control and to produce dry steam.

Correct near boiler piping is crucial to proper operation of

boiler and heating system.

Follow these recommendations carefully.

Place boiler in selected location as near chimney as

possible.

Install safety valve. Figure 5 and Warning on Page 8.

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

• Install elbows close to safety valve outlet and

downstream of union (if used).

Boiler is equipped with two 2" supply connections and

two 2" return connections, one each on both left and

right sides of boiler. Plug unused connections with

furnished 2" plug and 2 x ¾" bushing for drain valve.

When using both supply tappings to pipe system as

shown in Figure 6b , Page 10.

• Fit headers with header offsets, swing joints, or equip

with expansion joints, so thermal expansion and

contraction of header does not damage boiler. Do not

weld headers.

• Place system takeoffs from header between equalizer

and riser to header nearest equalizer. System takeoffs

must never be between two risers. If steam main goes

in two directions, place two takeoffs from header, one

for each main.

Recommended near boiler piping for gravity return

systems is shown in Figure 8 page 11. For gravity return

systems, bottom of lowest steam carrying pipe, dry

return or end of steam main, must be at least 28” above

normal water level line on left side of boiler.

Equip all boilers in gravity return systems with Hartford

Loop as shown in Figure 6a and 6b page 10.

Piping vertical risers from boiler to header, risers must

be minimum of 24" high above water line.

Steam riser(s) and header shall be 2" pipe.

Equalizer line shall be minimum 1-1/2" pipe size.

10.

Near boiler piping shall include 2" tee with female

adapter and cap located on supply line as shown for

skimming (i.e. surface blow-down).

11.

For pumped return systems, follow condensate pump

or boiler feed pump manufacturer’s instructions for

proper installation and hookup. See Table 4 and Figure

7 page 11.

12.

Connecting cold water supply to water inlet valve,

verify clean water supply is available. When water

supply is from well or pump, install sand strainer at

pump.
