Calculation of the combustion smoke weight
We propose the equation for calculating the combustion smoke weight based on the kW of methane burned:
X = 1,623 Y
X = combustion smoke weight (kg)
Y = kW burned
Connecting the condensate drain
The warm air heater is provided with a condensate drain pipe, positioned in the bottom part of gas box, which drains
the condensate produced in the heat exchanger.
A trap is also supplied, and the installer shall connect it to the heater’s condensate drain pipe and to the condensate
disposal system (see
Fig. 8
).
Unions must be watertight.
The disposal system piping must be calculated based on the condensate litres/hour (see the table on Chapter DATA
SHEET or table below), and its internal diameter must not be less than 20 mm.
The condensate disposal pipes must be made of synthetic material (such as PVC or corrosion-proof stainless steel).
Do not use galvanized steel pipes.
The trap provided must be installed always. It is complete with a float valve, to prevent fume leaks, and must be
filled with water before the first start-up.
The condensate disposal piping can be provided with trap and closed disposal pipe. Use this system for warm air
heaters installed in the heated ambient or inside a room.
Due to frost hazard, install an open piping (see the drawing below) for outdoor disposal systems.
To let the condensate out, make sure the warm air heater has been installed on a flat surface
condensate disposal piping must be installed at a level lower than the trap.

The pH of the condensate produced during combustion can be neutralised by a condensate
neutralisation kit.
