Choosing Installation Site
• Locate the vent terminal so that there are no obstacles around the termination and so that exhaust
can't accumulate. Do not enclose the termination with corrugated metal or other materials.
• Avoid places where res are common, such as those where gasoline,
benzene and adhesives are handled, or places in which corrosive gases
(ammonia, chlorine, sulfur, ethylene compounds, acids) are present.
Using the incorrect voltage may result in re or cracking.
• Avoid installation in places where dust or debris will accumulate.
Dust may accumulate and reduce the performance of the unit's fan.
This can result in incomplete combustion.
• Avoid installation in places where special chemical agents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
• Carbon Monoxide Poisoning Hazard. Do not install this Combi Boiler in a
recreational vehicle or on a boat.
• The manufacturer does not recommend installing the Combi Boiler in an
attic due to safety issues.
If you install the Combi Boiler in an attic:
• Make sure the unit will have enough combustion air and proper ventilation.
• Keep the area around the Combi Boiler clean. Dust may accumulate
and reduce the performance of the unit's fan. This can result in incomplete
combustion.
• Place the unit for easy access for service and maintenance.
• A drain pan, or other means of protection against water damage, is
required to be installed under the Combi Boiler in case of leaks.
DANGER
WARNING
Prohibited
* Locate the appliance in an area where leakage from the unit or connections will not result in damage
to the area adjacent to the appliance or to the lower oors of the structure. When such installation
locations cannot be avoided, a suitable drain pan, adequately drained, must be installed under the
appliance. The pan must not restrict combustion air ow.
* As with any water heating appliance, the potential for leakage at some time in the life of the product
does exist. The manufacturer will not be responsible for any water damage that may occur.
