Note: Compatibility charts do not take into consideration systems using additional heat emitters, DHW load etc.
Ensure the boiler selected meets all of the system requirements for loads generated by additional components.
It is the responsibility of the system designer to ensure proper sizing and equipment selection.
Proper sizing of systems components is crucial for proper
operation;
1. Obtain room by room heat loss and/or heat gain
2. Determine heating water temperature
3. Determine duct layout
Make sure a proper room-by-room heat loss and heat
gain for the dwelling is calculated using Manual J, HRAI,
ASHRAE or other approved sizing method.
