80% THERMAL EFFICIENCY MEANS
LOWER OPERATING COSTS
FAN ASSISTED COMBUSTION
• The blower is built into the low NOx burner assembly
• Complies with California SCAQMD Rule 1146.2 and
other air quality management districts with similar
NOx emission requirements of 14 ng/J or 20 ppm
AIR-FLAPPER
• A stainless steel air flapper is used inside the premix
system to replace externally mounted flue damper to
minimize the standby heat loss and to minimize the
overall heater height
METAL VENTING
• Rated Category I Appliance. Uses standard double
wall type “B” vent
• Can be commonly vented with other Category I
appliances
• Vent connects directly to the vent connector outlet
• An excellent choice for retrofit and upgrade
installations
• When common venting multiple BTL water heaters
into a common vent system, follow the common vent
tables in the current edition of the National Fuel Gas
Code book for Category 1, Fan assisted heaters.
WATER CONNECTIONS
• For ease of installation, all BTL’s feature water
connections on the top, front, and rear
• “The Eliminator” inlet water connection eliminates
harmful scale buildup, extending the life of the
product
• The front inlet connection must be used for the
Eliminator benefits
GLASSLINED TANK
• Permaglas
®
Ultracoat is the proprietary ceramic
coating developed by A. 0. Smith’s ceramic engineers
specifically for the heater
• Glassing is applied after the complete tank has been
assembled to give a seamless barrier against hot
water corrosion
INSTALLED COST SAVINGS
• The BTL uses a smaller vent diameter than a natural
draft water heater which saves on installation cost
FULLY AUTOMATIC DIGITAL CONTROLS
WITH SAFETY SHUTOFF
• Accurate, dependable control system
• Manual reset gas shutoff device for added safety
