these instructions
1. Inspect the inlet and outlet venting outside your house and free any
obstruction.
2. Contact a qualied service technician for assistance.

UserResponsibilities
This appliance must be installed and serviced by a licensed, certied and
trained service technician or the WarrantyisVoid. This appliance must
be serviced and inspected annually when operating in normal residential
applications. Other applications (e.g. commercial or other more strenuous
conditions) may require more frequent service and inspection. As the User of
this equipment, you are responsible for ensuring maintenance is performed
at the required intervals. It is also the Users responsibility to ensure Vent and
Combustion Air-Inlet terminations are kept clear of obstructions.

DANGER
The temperature at which injury occurs varies with the person's age and time of exposure.
Water temperature over 125°F/52°C can cause severe burns instantly or death from scalding.
The slower response time of disabled persons increases the hazards to them. Never allow small children
to use a hot water tap, or to draw their own bath water. Never leave a child or disabled person unattend-
ed in a bathtub or shower.
The appliance should be located in an area where the general public does not have access to the
temperature control.
Lower water temperatures should be used to avoid the risk of scalding. It is further recommended, in all
cases, that the domestic water temperature be set for the lowest temperature which satisfies the user’s
hot water needs. This will also provide the most energy efficient operation of the water heater and
minimize scale formation in the heat exchanger, thus prolonging the life of the unit.
Setting the domestic hot water temperature at 120°F/49°C will reduce the risk of scalds. Some
jurisdictions require settings at specific lower temperatures. The table below shows the approximate
time-to-burn relationship for normal adult skin.
Hot water temperatures required for automatic dishwasher and laundry use can cause scalds and burns
resulting in serious personal injury and/or death.

About 1/2 second
About 1-1/2 seconds
Less than 5 seconds
About 30 seconds
More than 5 minutes
To protect against injury, installing a tempering valve in the domestic hot water supply is
recommended. This valve will reduce point of discharge temperature by mixing cold and hot
water in branch supply lines. Such valves are available from the local plumbing supplier.

Glow Brand B85, B120 & B160 General Safety Warnings

WARNING
HOTWATERCANSCALD!
Water Temperatures over 125°F / 52°C can cause severe burns instantly or
death from scalds.
Children, disabled, and elderly are at highest risk of being scalded.
• Never leave then unattended in or near the shower, bathtub or sink.
• Never allow small children to use a not water faucet or draw their own bath.
To avoid any potential scald hazard or if codes require specic water
temperatures at the hot water faucet, the installer may
• Install a eld supplied thermostatic mixing valve at this appliance
• Set the thermostatic mixing valve to the lowest temperature which
satises your hot water needs.
TO AVOID INJURY:
• Feel and adjust water temperature before bathing or showering.
• Water drained from the system drain valve may be extremely hot.
• Make sure all connections are tight.
• Direct water ow away from any person.
WARNING
Close ll valve after any addition of water to the system, to reduce risk of water
escapement.
WARNING
Water quality has a signicant impact on the lifetime and performance of a
GLOW Boiler heat exchanger.
Improperly prepared water in a heating circuit may cause damage to the heat
exchanger through corrosion or fouling. Repeated or uncontrolled water lls will
increase the potential for damage.
High levels of dissolved solids or minerals may precipitate out of the uid onto
the hottest part of the heat exchanger, impairing heat transfer and resulting
in overheating and premature failure. The amount of solids that may form
on the heat exchanger will depend on the degree of hardness and the total
water volume in the system. A high water volume system with a low hardness
count may cause as much damage as a system with less volume and higher
hardness, so it is recommended to treat water so as to remove all dissolved
solids. Other water chemistry allowable limits are as follows:
• Acidity pH is to be between 6.5 and 8.5
• Chloride is to be less than 200 mg/l
• Iron is to be less than 0.3 mg/l
• Copper less than 1.0 mg/l
• Conductivity is to be less than 400μS/cm (at 25°C)
• Hardness is to be 7 Grains or less
WARNING
Should overheating occur or the gas supply fail to shut off, close the manual
gas shut-off valve to the appliance. Failure to follow instructions could result in
explosion causing property damage, serious injury or death.

WARNING
Should overheating occur or the gas supply fails 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
WARNING
Keep boiler area free and clear of combustible materials, gasoline, and other
ammable vapours and liquids.
WARNING
Combustion air must not be drawn from areas containing corrosive air from
swimming pools or spas, including air directly next to outdoor pools and spas.
WARNING
The boiler shall not be exposed to water leaks from piping or components
located overhead. This includes condensation dropping from non insulated cold
water lines overhead
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
qualied 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
Bacteria growth can develop in domestic hot water tanks and indirect water
heaters if the minimum water temperature is not set high enough to prevent its
growth.
WARNING
CRYSTALLINESILICA: Carefully read the warnings and handling instructions
in the Installation and Operating Instructions for Refractory Ceramic Fibers
before commencing any service work in the combustion chamber.
