Your HOTBLAST Furnace is designed to be a supplemental or 

central heating source for your home.  This Solid Fuel Furnace 

may  be  installed  in  conjunction  with  a  properly  operating 

central furnace that is listed or certified in accordance with 

nationally  recognized  safety  standards  and  equipped  with 

the  required  controls  and  other  safety  features  and  which 

has been installed in accordance with appropriate standards  

of the National Fire Protection Association with installation 

clearances specified in the furnace nameplate marking.  The 

installation must be accomplished by a qualified agency (one 

who is engaged in, and is responsible for, or is thoroughly 

familiar with the installation and operation of the gas, oil, and 

solid fuel burning heating appliances, who is experienced in 

such work, familiar with all the requirements of the authority 

having jurisdiction.)  The installation shall be in strict accordance 

with the manufacturer's installation instructions furnished with 

the solid fuel furnace.
The chimney connector of the furnace is to be installed to 

provide  clearances  to  combustible  material  not  less  than 

specified in the individual classifications and marked on the 

furnace.  The chimney connector must be connected to a 

chimney  suitable  for  use  with  residential  type  or  building 

heating appliances which burn solid fuel.
The Furnace is designed to operate in either parallel or series 

air flow arrangement with the central furnace or as a central 
furnace.

CENTRAL FURNACE INSTALLATION

As a central furnace, the unit functions independently of any 

other  system.  The  blower  will  come  on  when  the  plenum 
temperature reaches the setting on the blower control.

PARALLEL INSTALLATION (U.S. ONLY)

The design is such that when the blower comes on, the blower 

on the central system also comes on. The blower will only 

come on when the temperature in the plenum has reached 

the setting on the blower control.  This is to insure that there 

is sufficient warm air in the system to make it efficient for the 

unit to operate.  When the central system thermostat calls for 

heat, the central system will operate by the burner igniting 

and the blower coming on.  It is possible that both systems 

will operate simultaneously.  It is recommended that for the 

most efficient use of your HOTBLAST Furnace, that it be fired 

as much as possible in order to reduce the demand on your 

existing central heating system.  This unit has an optional 

forced draft kit that operates from a wall thermostat.  When 

the temperature falls below the setting on the wall thermostat, 

the forced draft will come on (U.S. Stove Option 11/DIKL)
The warm air supply outlet of the HOTBLAST Furnace shall 

not be connected to the cold air return of the central furnace, 

because the possibility exists of components of the central 

furnace overheating and causing the central furnace to operate 
other than is intended.

SERIES INSTALLATION

This type of installation uses only the blowers of the existing 

central  furnace.    The  solid  fuel  fan/limit  control  must  also 

control  the  functions  of  the  existing  furnace.   All  electrical 

power must come from a single branch circuit.
