MAINTENANCE

A qualified service person recommended by your YUNCA dealer should conduct an annual inspection
and undertake any maintenance required on your JERVOIS. Its venting and installation must be
checked to keep it running safely and efficiently. The following procedures should be performed only
by a qualified service person. The gas supply and electrical power should be isolated whenever any
maintenance procedures are undertaken.
Note: the door can only be removed after the heater has been turned off for long enough so that the
door has cooled to touching temperature.
Removing The Front Door
1. Remove the two rods that form the grill above the door. Sliding a rod to the left, allowing the right
hand end to be disengaged from the side panel. Moving the end clear and extracting the rod out
of the left hand side panel and clear. Repeat for the second rod.

thumb screws.
