FOR YOUR SAFETY, READ BEFORE OPERATING
• Check the GAS and WATER CONNECTIONS for leaks before ring unit for the rst
time.
• Open the main gas supply valve to the micro-boiler using only your hand to avoid any
spark. Never use tools. If the knob will not turn by hand, do not try to force it; call a
qualied service technician. Forced repair may result in a re or explosion due to gas
leaks.
• Be sure to check for the presence of leaking gas toward the bottom of the micro-boiler
because some gases are heavier than air and may settle towards the oor.
• Check the GAS PRESSURE. Refer to p. 25.

which automatically lights the burner.
• Check for PROPER VENTING and COMBUSTION AIR to the micro-boiler.
• Purge the GAS and WATER LINES to remove any air pockets.
• Do not use this micro-boiler if any part has been submersed under water. Immediately
call a qualied service technician to inspect the micro-boiler and to replace any damaged
parts.
IF YOU SMELL GAS:
• Do not try to start the micro-boiler.
• Do not touch any electric switches; do not use any phone in your building.
