Notes:
1. Determine the temperature rise required through the heater by subtracting winter design temperature from the desired
indoor temperature.
2. Select burner required:
BTUH = CFM x T x 1.08
.92
Formula includes 1.08 constant for heat content of air and .92 factor which is an average ratio of net and gross heating
values of common fuel gases. (92% sensible, 8% latent).
3. Contact Diversified Commercial Products Technical Support on temperature rise requirements greater than 120 F.
