Special instructions

NOTICE	This is a gas appliance and should be installed
	by a licensed electrician and/or certified gas
	supplier. Service must be performed by a
	qualified service installer, service agency or
	the gas supplier.

WARNING If the information in these instructions is not followed exactly, a fire or explosion may

result causing property damage, personal injury, or death.

This appliance MUST NOT be installed in any location where gasoline or flammable vapors are likely to be present, unless the installation is such to eliminate the probable ignition of gasoline or flammable vapors.

WARNING Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to this manual for assistance or additional information, consult a qualified installer, service agency or the gas supplier.

Checking equipment –

Upon receiving equipment, check for signs of shipping damage. Pay particular attention to parts accompanying the appliances which may show signs of being hit or otherwise being mishandled. Verify total number of pieces shown on packing slip with those actually received. In case there is damage or a shortage, immediately notify the carrier.

Apply enough water to the combustion chamber lining to prevent airborne dust.

Remove the combustion chamber lining from the appliance and place it in a plastic bag for disposal.

•NIOSH stated First Aid: Eye: Irrigate immediately. Breathing: Fresh air.

WARNING The combustion chamber insulation in this appliance contains ceramic fiber material. Ceramic fibers can be converted to cristobalite in very high temperature applications. The International Agency for Research on Cancer (IARC) has concluded, “Crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1).” Normal operating temperatures in this appliance are below the level to convert ceramic fibers to cristobalite. Abnormal operating conditions would have to be created to convert the ceramic fibers in this appliance to cristobalite.

The ceramic fiber material used in this appliance is an irritant; when handling or replacing the ceramic materials it is advisable that the installer follow these safety guidelines.

Do not use this appliance if any part has been under water. The possible damage to a flooded appliance can be extensive and present numerous safety hazards. Any appliance that has been under water must be replaced.

NOTICE	The ceramic fiber material used in this
	appliance is an irritant; when handling or
	replacing the ceramic materials it is advisable
	that the installer follow these safety guides.

REMOVAL OF COMBUSTION CHAMBER LINING OR BASE PANELS:

 Avoid breathing dust and contact with skin and eyes.

•Use NIOSH certified dust respirator (N95). This type of respirator is based on the OSHA

requirements for cristobalite at the time this

document was written. Other types of respirators may be needed depending on the job site conditions. Current NIOSH recommendations can be found on the NIOSH website at h t t p : / / w w w . c d c . g o v / n i o s h / h o m e p a g e . h t m l . NIOSH approved respirators, manufacturers, and phone numbers are also listed on this website.

•Wear long-sleeved, loose fitting clothing, gloves, and eye protection.

Warranty –

Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Experience has shown that improper installation or system design, rather than faulty equipment, is the cause of most operating problems.

1.Excessive water hardness causing a lime/scale build-up in the copper tube is not the fault of the equipment and is not covered under the manufacturer’s warranty (see Water Treatment and Water Chemistry).

2.Excessive pitting and erosion on the inside of the copper tube may be caused by too much water velocity through the tubes and is not covered by the manufacturer’s warranty (see Boiler Flow Rates and Temperature Rise for flow requirements).
