Installation & Operation Manual

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.

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).

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.

 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.

 

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

   NIOSH approved respirators, manufacturers, and 
 

  phone numbers are also listed on this website.

  • 

Wear long-sleeved, loose fitting clothing, gloves, 

 

  and eye protection.

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.

 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.



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.
