The following terms are used throughout this manual to bring attention to the presence of hazards of various risk levels.

WARNING

Indicates a potentially hazardous situation

which, if not avoided, could result in death,
serious injury or substantial property damage.

Important Product Safety Information

Refractory Ceramic Fiber Product

Warning:

The Repair Parts list designates parts that contain refractory ceramic fibers
(RCF). RCF has been classified as a possible human carcinogen. When
exposed to temperatures about 1805°F, such as during direct flame contact,
RCF changes into crystalline silica, a known carcinogen. When disturbed as a
result of servicing or repair, these substances become airborne and, if inhaled,
may be hazardous to your health.

AVOID Breathing Fiber Particulates and Dust

Precautionary Measures:

Do not remove or replace RCF parts or attempt any service or repair work
involving RCF without wearing the following protective gear:

CAUTION

Indicates a potentially hazardous situation

which, if not avoided, may result in moderate or

minor injury or property damage.

1. A National Institute for Occupational Safety and Health (NIOSH)
approved respirator

2. Long sleeved, loose fitting clothing

3. Gloves

4. Eye Protection

• Take steps to assure adequate ventilation.

• Wash all exposed body areas gently with soap and water after contact.

• Wash work clothes separately from other laundry and rinse washing

machine after use to avoid contaminating other clothes.

• Discard used RCF components by sealing in an airtight plastic bag. RCF
and crystalline silica are not classified as hazardous wastes in the United
States and Canada.

First Aid Procedures

• If contact with eyes: Flush with water for at least 15 minutes. Seek

immediate medical attention if irritation persists.

• If contact with skin: Wash affected area gently with soap and water.

Seek immediate medical attention if irritation persists.

• If breathing difficulty develops: Leave the area and move to a location

with clean fresh air. Seek immediate medical attention if breathing
difficulties persist.

• Ingestion: Do not induce vomiting. Drink plenty of water. Seek

immediate medical attention.

Basic Operation

CAUTION

Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical

supply to the pump. Instead, shut off the gas supply at a location external to the appliance.

En cas de surchauffe ou si I'admission de gaz ne peut être coupée, ne pas couper ni débrancher
l'alimentation électrique de la pompe. Fermer plutôt le robinet d'admission de gaz à l'extérieur de I'appareil.

Do not use this boiler if any part has been under water. Immediately call a qualied service technician to
inspect the boiler and to replace any part of the control system and any gas control which has been under

water.

A. General This boiler is equipped with controls for

proper operation. All controls must be in proper

working order. Contact a qualied service agency
to provide annual maintenance as specied in the

Installation, Operating and Service Instructions.

WARNING

Service on this boiler should be undertaken only
by trained and skilled personnel from a qualied
service agency.

1. Limit A device which automatically interrupts
boiler operation when the steam pressure exceeds
the set point. See Figure 1. Maximum allowable
pressure is 15 psi. Steam pressure can be read on the
Pressure Gauge.

2. Low Water Cutoff A device which automatically
interrupts boiler operation when the surface of the
boiler water falls to the lowest permissible operating
level. See Figure 1. The lowest permissible
operating level is indicated on a plate adjacent to

the gauge glass. The low water cutoff automatically

resets when water returns to its normal level. Boiler
operation resumes with a call for heat.

3. Blocked Vent Switch See Figure 7. A device

which automatically interrupts boiler operation
when excessive vent system blockage occurs. Do

not attempt to place boiler in operation if control
was activated to interrupt boiler operation. Contact

a qualied service agency.

CAUTION

Do not reset Blocked Vent Switch unless a
qualied service agency has determined and
corrected the cause of any blockage in the vent

system or chimney.

4. Flame Rollout Switch See Figure 2. A device

which automatically interrupts boiler operation
when ames or excessive heat are present in the
vestibule. The control is a single use device. Do not

attempt to place boiler in operation if control was
activated to interrupt boiler operation. Contact a

qualied service agency.

Figure 2: Flame Rollout Switch

B. Instructions to place boiler in operation and to turn

off boiler are shown on the Lighting or Operating
Instruction label posted on the inside of the front
removable door. See Figure 3 for front door removal
instructions. The Lighting/Operating Instructions are
also shown in Figures 4, 5 and 6. The boiler model
number is printed on the rating label (see Figure 1).

5. Intermittent Ignition System See Figure 1. The

Electronic Ignition (EI) System consists of:

a. an ignition module to initiate, monitor and stop

burner operation.

b. a combination gas valve to regulate gas ow to

burners.

c. a pilot burner to provide the ignition source for

main burners.

6. Continuous Ignition System (Standing Pilot) See

Figure 1. The Continuous Ignition System consists
of:

a. a combination gas valve to regulate gas ow to

burners.

b. a constant burning pilot burner to provide the

ignition source for main burners.

c. a thermocouple to sense pilot burner ame and

cause combination gas valve to turn off main

burner and pilot burner gas ow should pilot
burner ame extinguish.
