Installation & Operation Manual
Please read before proceeding
Installer – Read all instructions, including 
this manual and the Crest Service Manual, 
before installing.  Perform steps in the 
order given.
User – This manual is for use only 
by a qualified heating installer/
service technician.  Refer to the User’s 
Information Manual for your reference.
Have this boiler serviced/inspected by 
a qualified service technician, at least 
annually.
Failure to comply with the above could 
result in severe personal injury, death or 
substantial property damage.
Failure to adhere to the guidelines on this 
page can result in severe personal injury, 
death, or substantial property damage.
When servicing boiler –
• To avoid electric shock, disconnect electrical supply 
  before performing maintenance.
• To avoid severe burns, allow boiler to cool before 
 performing 
maintenance.
Boiler operation –
• Do not block flow of combustion or ventilation air to 
 the boiler.
• Should overheating occur or gas supply fail to shut off, 
  do not turn off or disconnect electrical supply to 
  circulator.  Instead, shut off the gas supply at a location 
  external to the appliance.
• Do not use this boiler 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.
Boiler water –
• 
Thoroughly flush the system (without boiler 
  connected) to remove sediment.  The high-efficiency 
 heat exchanger can be damaged by build-up or 
  corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing 
  compounds in the boiler system.  Gaskets and seals in 
 the system may be damaged.  This can result in 
  substantial property damage.
• Do not use “homemade cures” or “boiler patent 
  medicines”.  Serious damage to the boiler, personnel, 
  and/or property may result.
• Continual fresh make-up water will reduce boiler life.  
  Mineral buildup in the heat exchanger reduces heat 
  transfer, overheats the stainless steel heat exchanger, 
  and causes failure.  Addition of oxygen carried in by 
  makeup water can cause internal corrosion in system 
  components.  Leaks in boiler or piping must be repaired 
  at once to prevent the need for makeup water.
Freeze protection fluids –
• NEVER use automotive antifreeze.  Use only inhibited 
 propylene glycol solutions, which are specifically 
  formulated for hydronic systems. Ethylene glycol is 
  toxic and can attack gaskets and seals used in hydronic 
 systems.
When calling or writing about the boiler 
– Please have the boiler model and serial 
number from the boiler rating plate.
Consider piping and installation when 
determining boiler location.
Any claims for damage or shortage in 
shipment must be filed immediately 
against the transportation company by 
the consignee.
Factory warranty (shipped with unit) does 
not apply to units improperly installed or 
improperly operated.
