PART 1 GENERAL INFORMATION
1.1
INTRODUCTION
The
Advantus
is a condensing, forced draft, fire tube appliance 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
Advantus
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 down to 10% for
models AV500 & AV600 and down to 4.5% for models AV800 to AV1800 and 4.0% for models AV2000 to AV4000. The
Advantus
models
500 & 600 use a single automatic gas valve and operate on the principle of negative pressure. As the fan varies in speed it generates a
varying negative pressure at the fan suction which draws in a corresponding amount of gas.
The
Advantus
models 800-4000 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 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 the gas valve works on the principle of negative pressure.

SPECIAL INSTRUCTIONS TO OWNER
This 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.
CAUTION
It is important that all gas appliances are installed by a qualified installer/technician that is trained by

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.
