Warning

In areas of high snow fall, users must check side wall exhaust vent and air intake terminations

on a regular basis to ensure blockages do not occur.

Warning

Do not use this boiler if any part has been under water. Immediately call a qualified service

technician to inspect the boiler and to replace any part of the control system and any gas

control that has been under water.

Warning

Improper installation, adjustment, alteration, service or maintenance can cause property

damage, personal injury, or loss of life. Read and understand the entire manual before

attempting installation, start-up, operation, or service. Installation and service must be

performed only by an experienced, skilled installer or service agency.

Failure to follow all instructions in the proper order can cause personal injury or death. Read

all instructions, including all those contained in component manufacturers’ manuals before

installing, starting up, operating, maintaining, or servicing the unit.

Warning

Close fill valve after any addition of water to the system, to reduce risk of water escapement.

Warning

Disconnect power supply before any wiring/service is performed. Failure to do so could result

in damage to unit and/or electric shock.
