Features

Features

The BTN-80 and BTN-100 are equipped with a factory-mounted blower that is pre-wired. This blower produces a pre-ignition draft of make-up air prior to burner ignition and provides more efficient control of heat and helps ensure an adequate supply of make-up air. Prior to ignition, the control proves a working draft.

Factory-installed Blower
  • Control proves draft prior to ignition
  • No draft hood or barometric damper required
  • Blower is factory mounted with a 6-foot power cord: requires 120 V, 3 amp or less electrical system connection
Intelli-Vent™ Gas Control
  • Equipped with nearly indestructible silicon nitride hot surface igniter
  • Advanced electronics for more precise control of water temperature
  • Easy-to-understand system diagnostics
Rated as Category I Appliance
  • Category I appliance: uses standard metal, single-wall or "B"-type vent
  • Can be commonly vented with other Category I appliances
  • Vent connects directly to blower outlet
Fully Automatic Control System
  • Auto reset gas shutoff device prevents excessive water temperature
  • Adjustable thermostat with 120 to 180 ºF range
  • Gas pressure regulator
Factory Equipped With Dual Burners

Glass Lined Tank
  • Exclusive CoreGard™ anode rods with stainless steel core provide additional corrosion protection
Handhole Cleanout
  • Allows easy access to tank interior for cleaning
