NOTE: Ratings shown are for elevations up to 2,000 feet. For
elevations over 2,000, reduce ratings at the rate of 4% for each
1,000 feet above sea level.
(a) Add 1-1/8" to overall height for combustible floor shield option
(b) 1" or 1-1/4" contingent on boiler type or code requirements
(c) 3" NPT on single-pass option
(d) Propane input/output is 92% of standard values

NOTES:
• Values represent maximum flows and pressure drops for closed heating systems
• Maximum acceptable flow through heat exchanger tubes is 90 GPM (two-pass); 200 GPM (one-pass)
• Single-pass heat exchangers are to be used only when flow rates exceed the allowable for two-pass
