Maximum Heating Power Adjustment 2.3.1
The maximum heating power can be adjusted to between the
maximum and minimum power allowed by the boiler.
The display shows the heating power value between 100% (“100” on
the display) and 0% (“0”) of this interval.
To check the maximum heating power, access menu 2/sub menu 3/
parameter1 (231).
Check the value. If necessary, modify it as indicated in Table 29.
Checking Ignition Power 2.2.0
To check the Ignition power access menu 2/sub menu 2/parameter
0 (220).
If necessary, modify it as indicated in Table 29.
Heating Ignition Delay Adjustment 2.3.5
This parameter is used to manually (0) or automatically (1) set the
heating ignition delay time. This is the time the boiler delays igniting
the burner after it has met the central heating mode setpoint and
switched off.
To change this parameter, access menu 2/sub menu 3/parameter 5
(2.3.5).
After selecting manual, access the successive parameter 2.3.6 to set
the delay between 0 and 7 minutes.
Automatic selection means that the boiler will establish the delay
time based on the set-point temperature.
D. Converting the Appliance from Natural Gas to
Propane Operation
HTP boilers are factory set to operate on Natural Gas. BEFORE
OPERATING ON PROPANE the boiler must be converted to Propane
using the included conversion kit specific to the boiler model.

CONVERSION INSTRUCTIONS
For Qualified Technician
Installation Instructions
This conversion kit shall be installed by a qualified
service agency in accordance with the manufacturer’s
instructions and all applicable codes and requirements
of the authority having jurisdiction. If the information
in these instructions is not followed exactly, a fire, an
explosion or production of carbon monoxide may result
causing property damage, personal injury or loss of
life. The qualified service agency is responsible for the
proper installation of this kit. THE INSTALLATION IS NOT
PROPER AND COMPLETE UNTIL THE OPERATION
OF THE CONVERTED APPLIANCE IS CHECKED AS
SPECIFIED IN THE MANUFACTURER’S INSTRUCTIONS
SUPPLIED WITH THE KIT, WHICH NECESSITATES
THE USE OF A CALIBRATED CO2/O2 AND CO
COMBUSTION ANALYZER.
WARNING
Figure 72 - Conversion Kit Instruction Cover
WARNING
!
The instructions included with the conversion kit CANNOT be
used to convert other HTP appliance models. The instructions
apply ONLY to the models referenced within. Contact HTP for the
availability of conversion kits and instructions for other models.
Failure to apply these instructions properly may result in dangerous
Carbon Monoxide levels, fire, or explosion, leading to property
damage, serious personal injury, or death.
ATTENTION:
LIQUEFIED PETROLEUM (LP) PROPANE
Liquefied Petroleum (LP) propane gas is heavier than air;
therefore, it is imperative that your boiler is not installed in a
pit or similar location that will permit heavier than air gas to
collect.
Local Codes may require appliances fueled with LP gas be
provided with an alarm or an approved means of removing
unburned gases from the room. Check your local codes for this
requirement.
