1.1 INTRODUCTION
The DynaFlame is a fan assisted appliance based on push
through design which offers several venting options. Heat
output is controlled by a one to one air/gas ratio control gas
valve which provides seamless modulation. The
DynaFlame provides central heating and/or domestic hot
water at working pressure up to 160 PSI. It is designed for
use with a fully pumped and pressurized system. The
boiler/water heater will automatically modulate to provide
heat outputs between 100% to approximately 35% of rated
input on non-condensing models and down to 20% on near
condensing (DFX) and condensing models.
The DynaFlame works on the principle of differential
pressure. The operation of the fan will generate a
differential pressure, which the gas/air ratio control gas
valve will match 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 entire
operating range.
DynaFlame Non-Condensing
In this series most of the sensible heat value is being
transferred into the water. The unused portion of the
sensible heat and all the latent heat is released through the
exhaust vent. The overall efficiency of the DynaFlame is
being improved by incorporating preheat of intake
combustion air which consequently maintains the outer
panels cool and thus reduces jacket loss.
DynaFlame Near Condensing
In this series most of the sensible heat value is being
transferred into the water. The unused portion of the
sensible heat is too small to maintain flue products in a
gaseous state. Therefore condensation is formed in the
vent. The defining characteristics of the DFX are reduced
vent sizes at reduced equivalent vent lengths of 50 ft, and
continuous modulation permitted down to 20% of input.

DynaFlame Condensing
In this series most of the sensible heat value is being
transferred into the water. The unused portion of the
sensible heat and most of the latent heat is absorbed by the
Condenser Heat Recovery Module (CHRM).

1.2 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
competent person. It is in your own interest and that of
safety to ensure that all local codes, and all the following
“NOTES” and “WARNINGS” is complied with.
To Install, service or adjust this appliance, it is imperative
that a competent serviceman that is qualified by Camus
Hydronics utilize a combustion analyzer with CO
2
, CO, and
draft gauge, to set the appliance according to Camus
Hydronics recommendation, prior to commissioning.
