PART 1 GENERAL INFORMATION
1.1 INTRODUCTION
The Avenger
is a condensing, forced draft, fire tube boiler and water heater utilizing a premix power burner based on a push through
design which offers several venting options. Heat output is controlled by air/gas ratio control gas valves which provide seamless
modulation. The Avenger provides central heating or domestic hot water at working pressures up to 160 PSI. It is designed for use with
a pumped and pressurized system. The boiler/water heater will automatically modulate to provide heat outputs between 100% and the
minimum input.
All Avenger models use two automatic gas valves - one at the low end and one at the high end. The High-End Gas Valve works on the
principle of differential pressure. Operation of the fan along with modulating air actuator, generates a differential air pressure, which the
air/gas ratio control gas valve matches on the gas side. The steady state efficiency is maintained across the entire range of modulation.
Air and gas are metered in precise proportion (1:1 Ratio) to modulation signal, allowing combustion characteristics, which determine
efficiency, to remain the same over the entire operating range. The Low-End Gas Valve works on the principle of negative pressure.
1.2 SPECIAL INSTRUCTIONS TO OWNER
This installation and service manual supplies information for the installation, operation and servicing of the appliance. It is strongly
recommended that this manual be reviewed completely before proceeding with an installation.
It is important that all gas appliances are installed by a qualified installer/technician that is trained by Camus Hydronics Limited. It is in
your own interest and that of safety to ensure that all local codes, and all the following “NOTES” and “WARNINGS” are complied with.
Installing, servicing or adjusting this appliance should be performed only by a qualified installer/technician that is trained by Camus
Hydronics Limited. The serviceman must utilize a combustion analyzer with CO
2,
CO, and draft gauge to set the appliance according
to Camus Hydronics Limited’s recommendations, prior to commissioning.
