electrical standards and codes.
All plumbing and piping connections should be carried out by qualified personnel and in accordance to local
standards and codes.

1.4 Safety Systems
The following safety systems are included in the Janfire NH pellet burner:
A non-combustible drop shaft protects against reverse combustion.
A temperature sensor in the drop shaft gives a reading which, if exceeds 158°F (70°C) reduces the
burner output. If the temperature exceeds 203°F (95°C), the burner shuts down.
A flexible tube of special plastic.
The tube between the external feeding auger and the burner is constructed of a special plastic
material, which melts (not burns) at high temperatures and breaks the contact between the pellet
feeding auger and burner.
Circuit breaker/Door switch
The burner is equipped with a micro-switch circuit breaker, which prevents the burner from operating
when detached from the boiler.
Two electrical fuses to protect electrical components from over current draws.
A 10 Amp resettable fuse is located above burner wiring terminal to protect internal electronics.
A 15 Amp fast blow fuse protects the ignition heating coil.
Speed sensor on the fan monitors fan speed.
NOTE:
The Janfire NH pellets burner should have ample clearance in accordance to local codes.
