Gas Burner first start
The PCH burners are supplied with factory settings
according to model number gas selection. They are
tested for the gas specified on the burner nameplate.
However it is required to
- Check the gas category
- Check the gas intake pressure on the gas valve
- Perform the combustion analysis to verify
that the level of flue gases corresponds to
the data contained in general data table or in
manufacturer IOM manual.
When turned on for the first time, the pilot burner may
not ignite due to air kept in gas hose. There is the need
to reset the equipment and repeat the operation until
gas hose is purged and it ignites.
Consult electrical drawing and supplier IOM shipped
with the unit.

Premix burner working cycle
1. Heat request signal coming from CH536
2. Burner fan starts to pre-wash combustion chamber
3. EV1 and EVP gas valves open to allow gas to feed
pilot burner
4. Start up electrode gives ignition sparks on pilot
burner
5. EV2 main gas valve opens to gas feed main burner
6. Combustion starts thanks to pilot flame ignition
7. Pilot and main burners work together for a shor time,
then the electronic boards close EVP and stops the
pilot
