FREEZE PROTECTION FLUIDS
CAUTION
Never use automotive or standard glycol antifreeze, or even ethylene glycol made for hydronic systems. Use only
inhibited propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic
and can attack gaskets or seals used in hydronic systems. Ensure that the glycol used never exceeds 35% of the
systems volume as this may damage the systems components.
Consider piping and installation when determining a location for the boiler. Any claims for damage or shortage in a
shipment must be filed immediately against the transportation company by the consignee.
CONDENSATE REMOVAL SYSTEM
This vent is to be used on a efficiency condensing appliance; therefore this venting has a condensate removal system. Condensate
is nothing more than water vapor, derived from the combustion products. It is very important that the condensate line is sloped
away from the vent and down to a suitable inside drain. A condensate filter, if required by local authorities can be made up of lime
crystals; marble or phosphate chips that will neutralize the condensate. This can be done in the field by the installer. It is also very
important that the condensate line is not exposed to freezing temperatures, or any other type of blockage. Plastic tubing must be
the only material used for the condensate line. Steel, brass, copper or others will be subject to corrosion or deterioration. A second
vent may be necessary to prevent condensate line vacuum lock if a long horizontal run is used. Also, an increase in pipe size may
be necessary to drain properly. Support of the condensation line may be necessary to avoid blockage of the condensate flow.
CAUTION
The condensate line must remain unobstructed, allowing free flow of condensate. If condensate is allowed to freeze in
the line or if the line is obstructed in any other manner, condensate can exit from the boiler condensate trap, resulting
in potential water damage to property.
Note:
Use materials approved by the authority having jurisdiction. In the absence of an authority, PVC and CPVC pipe must comply with
ASTMD1785, F441 or D2665. Cement and primer must comply with ASTM D2564 or F493. For Canada, use CSA or ULC certified
PVC or CPVC pipe, fittings and cement. When installing a condensate pump, select one approved for use with condensing boilers
and furnaces. The pump should have an overflow switch to prevent property damage from condensate spillage. Condensate from
the boiler will be slightly acidic (typically with a pH from 3.0 to 4.0). Install a neutralizing filter if required by local codes.
IMPORTANT
Do not use the boiler if any section of it has been subjected to water or submerged in water. Immediately call your service company
to inspect and replace any part of the control system and gas components which have been subjected to water or submerged in
water.
CARBON MONOXIDE
The installation of carbon monoxide detectors is highly recommended by the U.S. Consumer Product Safety Commission for
buildings with gas burning equipment. Sources of carbon monoxide include exhaust vents for gas appliances or wood burning
fireplaces that are not properly vented, malfunctioning furnaces and exhaust fumes from idling cars. Carbon monoxide is a
colorless and odorless gas that is highly toxic. It can interfere with the delivery of oxygen by the blood to the body. Exposure to low
levels of CO can cause headaches, confusion, nausea, dizziness, fatigue, and shortness of breath. High level exposure of CO can
cause impaired vision, convulsions, coma and possibly death. Have a qualified service technician inspect the heating equipment
exhaust vent pipes and chimney flues on a yearly basis. In winter, inspect the exhaust vents for the dryer, furnace, wood burning or
gas stove, fireplace and heat recovery ventilator to ensure they are not obstructed by snow build-up. Carbon monoxide detectors
should be installed and maintained in buildings that house gas burning equipment. It is recommended to use a carbon monoxide
detector that is in compliance with a nationally recognized standard such as ANSI/UL 2034- 2002 or CSA 6.19-01.
WATER PIPE FREEZING HAZARD
The boiler is designed to provide a comfortable and warm environment and is not designed for the prevention of frozen water
pipes. In the event an unsafe condition occurs, the boiler has been designed and equipped with several safety devices that will
shut down the boiler and stop it from restarting. If the boiler is dormant for an extended period of time during cold winter weather,
the water pipes may freeze and burst which can result in extensive water damage and lead to mold growth. A variety of molds
can cause serious health and respiratory problems. If water damage should occur, immediately dry the affected areas to avoid the
possibility of mold growth. If the building will be empty for an extended period of time in cold winter conditions, then the following
steps should be taken:
• Turn off the building's water supply, drain the pipes and add some antifreeze to the potable water for the toilet tanks and drain
traps.
• Have the building monitored and checked during cold winter weather and call a qualified service technician if necessary.
• Remote temperature sensors are available which will alert someone if freezing conditions occur in the building.
WARNING
Serious property damage and/or personal injury can occur if the pipes are not protected from freezing, possibly
resulting in pipes bursting or the boiler shutting down.Turn off the water supply and drain the water pipes or protect
them from freezing when leaving the home unattended for long periods of time during very cold weather conditions.
