and, in the United States, to the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA54. In Canada, the

installation must conform to the latest edition of CSA B149.1 Natural Gas and Propane Gas Installation Code, and/

or local codes. Where required by the authority having jurisdiction, the installation of Brute LX boilers must conform to

the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1. Any modications

to the boiler, its gas controls, or wiring may void the warranty. If eld conditions require modications, consult the

factory representative before initiating such modications.

1.1 Introduction

This manual provides information necessary for the

installation, operation, and maintenance of Bradford

White Corp Brute LX appliances. Read it carefully

before installation. All application and installation

procedures should be reviewed completely before

proceeding with the installation. Consult the Bradford

White Corp factory, or local factory representative, with

any problems or questions regarding this equipment.

Experience has shown that most operating problems are

caused by improper installation.

All installations must be made in accordance with

1) American National Standard Z223.1/NFPA54-Latest

1.3 Rating Plate

The Rating Plate is located on the metal pan behind

the lower plastic panel. Figure 1. It contains Model

Nomenclature, Manufacture Date, Model Number,

Serial Number, Output Rating, and all other information

pertaining to your Brute LX. .

1.2 To Open the Brute LX

To open the Brute LX for maintenance and servicing,

the upper and lower plastic panels are designed to 'pop'

o when they are pulled forward. See Figure 1 and

Figure 3. This will expose the top metal panel which

covers the heat exchanger, and the lower panel which

holds the low voltage connections and covers the pump

and other lower components.

To remove these panels for further access into the

Brute LX, there are two screws that hold each panel in

place. Remove the 2 screws on the upper panel and slide

the upper metal panel up and out. For the lower panel,

remove the 2 screws and hinge the lower metal panel

downward.

The center panel containing the On/O Switch, Gauges,

and User Interface is not removable.

Edition “National Fuel Gas Code” or

2) CSA B149.1 “Natural Gas and Propane Installation

Code” and with the requirement of the local utility or

other authorities having jurisdiction. Such applicable

requirements take precedence over the general

instructions contained herein.

All electrical wiring is to be done in accordance with

the local codes, or in the absence of local codes, with: 1)

The National Electrical Code ANSI/NFPA No. 70-latest

Edition, or 2) CSA STD. C22.1 “Canadian Electrical

Code - Part 1”. This appliance must be electrically

grounded in accordance with these codes.

B. AVANT D'UTILISER, vérifiez s'il n'ya pas d'odeur de gaz prés de l'appareil. Vérifiez

s'il n'ya pas d'odeur de gaz prés du plancher, car le gaz est plus lourd que l'air et peut

se déposer sur le plancher.

QUE FAIRE EN CAS D'ODEUR DE GAZ

• N'essayez pas d'allumer n'importe quelque appareil que ce soit.

• Ne touchez pas a un commutateur electrique. N'utilisez pas le téléphone de votre résidence.

• Appelez immédiatement votre fournisseur de gaz en utilisant le téléphone de votre

voisin. Suivez les instructions de votre fournisseur de gaz.

• Si vous ne pouvez joindre votre fournisseur de gaz, appelez le service des incendies.

C. N'utilisez pas cet appareil si l'une des pièces a été plongée sous l'eau.

Communiquez immédiatement avec un technicien de service qualifie afin qu'il inspecte

l'appareil et remplace toute pièce du système de commande et toute commande de

gaz qui aurait été plongée sous l'eau.

1.9 The Condensate Trap

The Brute LX is a high eciency condensating unit. It

requires that the included condensate trap be installed

along with a proper drain.

We recommend that the condensate trap for the wall

mounted Brute LX be installed before mounting it to the

wall. For instructions on how to do this, see Figure 12,

Figure 13 and Figure 14 starting on page 21 in Section 6

of this manual.

____________________________________________

NOTE: It is easier to install the Condensate Trap to the

Wall Mounted Brute LX before it is mounted to the wall.

____________________________________________

1.10 The Pressure Relief Valve (PRV)

The Pressure Relief Valve on the wall mounted unit must

be installed as the rst piping component.

See Section 6.9 starting on page 23 'Piping Schematics'
