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) - see page 60.
Check the value. If necessary, modify it as indicated in Table 32.
Checking Ignition Power 2.2.0
To check the Ignition power access menu 2/sub menu 2/parameter 0
(220) - see page 60.
If necessary, modify it as indicated in Table 32.
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)- see page 60.
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
NTI 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.
WARNING
These instructions CANNOT be used to convert NTI appliance
models not referenced within these instructions. Contact NTI 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.

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.
