nStaLLation

:

1. Install the wall thermostat in a location that is not to close too the unit but will effectively heat the 

desired area.

Figure 46: Thermostat wire placement.

2. Install a 12 or 24 Volt Thermostat using an 18 x 2 

gauge wire from the unit to the thermostat.

If the unit has been placed in the HI / LOW mode, the unit 

will be taken to a low or idle setting when the thermostat 

is not calling for heat. When the thermostat calls for 

heat, the unit will go to the setting that is displayed on 

the control board Heat Indicator. If the heating load is 

not great enough when the stove is on low, the high limit 

switch will turn the stove off and the switch will have to 

be manually reset. To reset the high limit switch, remove 

the right cabinet side. The switch is found behind the 

control panel. Avoid setting off the high limit switch.

*To achieve Maximum 

efficiency  of 75.1% HHV 

you will need to  purchase 

meridian top vent adapter 

kit. (50-4117)

Use the sheet metal screws 

to attach the kit to the rear 

of the unit. Please see 

kit instruction manual for 

more detailed installation 

instructions.
