Boiler service and maintenance
The Boiler manual is for use only by a qualified heating installer/service technician. Refer only to this User’s
Information Manual for your reference. Improper installation, adjustment, alteration, service or maintenance
can cause property damage, personal injury (exposure to hazardous materials) or loss of life. Installation and
service must be performed by a qualified installer, service agency or the gas supplier (who must read and follow
the supplied instructions before installing, servicing, or removing this boiler. This boiler contains materials that
have been identified as carcinogenic, or possibly carcinogenic, to humans).

nance.
To avoid severe burns, allow boiler to cool before performing maintenance.
You must maintain the boiler as outlined in this manual and
up and serviced at least annually

by a qualified service technician to ensure boiler/
have the boiler started
Boiler operation —
Do not block flow of combustion or ventilation air to boiler. This boiler is equipped
with a control which will automatically shut down the boiler should air or vent be
blocked. If vent or air blockage is easily accessible and removable, remove it. The boiler
should attempt to restart. If blockage is not obvious or cannot be removed, have the
boiler and system checked by a qualified service technician.
Do not allow contaminated air to enter the boiler air inlet pipe. See page 4 for de-
tails.
Should overheating occur or gas supply fail to shut off, do not turn off or disconnect
electrical supply to boiler. Instead, shut off the gas supply at a location external to
the appliance.
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, which has been under water.
Boiler water —
Have boiler water chemistry checked at least annually by a qualified service techni-
cian.
DO NOT use petroleum-based cleaning or sealing compounds in boiler system. Gas-
kets and seals in the system may be damaged. This can result in substantial property
damage.
DO NOT use “homemade cures” or “boiler patent medicines”. Serious damage to
boiler, personnel and/or property may result.
Continual fresh makeup water will reduce boiler life. Mineral build-up in boiler heat
exchanger reduces heat transfer, overheats the metal, and causes heat exchanger failure. Addition of oxygen can cause internal corrosion in system components. Leaks
in boiler or piping must be repaired at once to prevent makeup water.
Do not add cold water to hot boiler. Thermal shock can cause boiler heat exchanger
to crack.

Prevent combustion air contamination
If the boiler combustion air inlet is located in any area likely to cause contamination, or if products which
would contaminate the air cannot be removed, you must have the combustion air and vent re-piped and
terminated to another location. Contaminated combustion air will damage the boiler, resulting in possible severe personal injury, death or substantial property damage.
Do not operate an Ultra boiler if its combustion air inlet is located in a laundry room or pool facility, for
example. These areas will always contain hazardous contaminants.
Pool and laundry products and common household and hobby products often contain fluorine or chlorine
compounds. When these chemicals pass through the boiler, they can form strong acids. The acid can eat
through the boiler wall, causing serious damage and presenting a possible threat of flue gas spillage or
boiler water leakage into the building.
Please read the information listed below. If contaminating chemicals will be present near the location of
the boiler combustion air inlet, have your installer pipe the boiler combustion air and vent to another
location, per the Boiler manual.
