Peerless - PF-399-N - 399,000 BTU - Gas-Fired High Efficiency Condensing Commercial Hot Water Boiler - Natural Gas - 93.4% Thermal Efficiency - Direct Vented - 0 to 10,000 Foot Altitude - Packaged - MPN: 0007006
Product Overview

For over a century Peerless has dedicated itself to making efficient, durable boilers. The PureFire line is emblematic of these qualities. This is a direct vent, condensing boiler with DHW priority and an internal condensate system. A stainless steel burner and heat exchanger discourage corrosion and wear. The combination of first-rate components and advanced technology make the PF-399-N an excellent choice for heating your home or business. The PF-399-N is compact and requires zero clearance to combustibles, making installation flexible and easy. Front-mounted controls with clear error displays confer that same simplicity to maintenance. Between the efficiency-enhancing features and the quality construction, Peerless PureFire Hot Water Boilers are an attractive and reliable heating solution.

Product Features

Modulating Burner
The PF-399-N uses a modulating burner to scale heating to your needs. This burner will vary its output based on your desired temperature, preventing the overuse of energy. Anti-cycling times set during installation prevent short-cycling.

LoNOx Operation
Not only is the PF-399-N environmentally friendly by virtue of its tremendous efficiency, but its LoNOx operation means significantly reduced emissions and a minimal environmental footprint.

Equipped for Outdoor Reset
PureFire hot water boilers include an outdoor temperature sensor and outdoor reset capability. With outdoor reset control to balance your heat production, the PF-399-N improves efficiency and comfort automatically.

Condensate System
All Peerless PureFire boilers have an internal condensate system. This system protects your heat exchanger from condensate backup with a float switch. It also neutralizes the acidity of any condensate produced. The result is a clean, efficient, and safe boiler.

The PF-399-N hot water boiler may be converted—from natural gas to propane and vice versa—in the field by a trained and qualified professional. Also, the PureFire line supports cascading; up to 16 PureFire boilers may be connected together. These options mean that even if your heating requirements change over time, the PureFire is still a solution.
