temperature may be less than 120°F, such as in-floor radiant systems, snow melt systems or other systems where a “cold start” is expected frequently due to thermostat setbacks, etc. See Figure 11.

b.Any system where the temperature rise across the heat exchanger is above 30°F (see Section 5 and Figure 7).

2.Combustion air grates for openings sized in accordance with Section 3.1.

3.Field interlock wiring for any motorized combustion air louvers to ensure the boiler does not fire if motorized louvers do not open.

1.5.3 Diagnostic Tools

The following materials are needed to verify

correct installation:

1.Gas manometer to verify gas pressure

2.Strap-on, digital or infrared thermometer to check temperature rise across the heat exchanger.

3.Suggested: Draft gauge and combustion test equipment.

Installation Instructions

2.1 Introduction

WARNING

Improper installation or maintenance can cause nausea or asphyxiation from carbon monoxide in flue gases which could result in severe injury, or death.

AVERTISSEMENT

Une installation ou un entretien in adéquat peut causer la nausée ou l’asphyxie en raison du monoxyde de carbone présent dans les gaz de combustion et même entrainer des blessures graves ou la mort.

Install the Brute Mini boilers and vent dampers in accordance with the procedures in this manual, local codes and ordinances, and in accordance with the latest edition of the appropriate national code (see Section 1.3 “Codes and Standards”).

All gas-fired products require correct installation to assure safe operation. The requirements for boilers include the following:

1.Field assembly

2.Appropriate site location (clearances) and flooring

3.Sufficient combustion and ventilation air

4.Properly sized gas meter and piping

5.Proper electrical wiring (if required)

6.Adequate water flow

This manual provides the information needed to

meet these requirements. Review all application and installation procedures completely before continuing the installation.

NOTE: The Brute Mini boiler is approved for indoor installation only.
