THIS QUALITY CONBRACO SAFETY RELIEF VALVE, ALONG WITH PROPER
INSTALLATION, USE AND MAINTENANCE, WILL PROVIDE MANY YEARS OF
RELIABLE SERVICE AND PROTECTION AGAINST EXCESSIVE PRESSURE
BUILD-UP OF WATER/STEAM. USE OF THIS VALVE FOR ANY OTHER
PURPOSE OR MEDIA PLACES ALL RESPONSIBILITY UPON THE USER.
BEFORE INSTALLING VALVE, OR OPERATING EQUIPMENT TO WHICH IT IS
INSTALLED, READ ALL INSTRUCTIONS CAREFULLY. ALWAYS WEAR
PROPER SAFETY EQUIPMENT.

A

OPERATING INSTRUCTIONS

IF ADDING WATER TO A BOILER, DO NOT ALLOW WATER TO FLOW
THROUGH SAFETY VALVE AS SEDIMENT OR DEBRIS MAY BE DEPOSITED ON
SEATING SURFACE.
TO ACHIEVE TOPMOST PERFORMANCE AND MAXIMUM SERVICE LIFE, IT IS
NECESSARY TO MAINTAIN A PROPER PRESSURE MARGIN BETWEEN THE
SET PRESSURE OF THE SAFETY VALVE AND THE EQUIPMENT'S OPERATING
PRESSURE.
THE RECOMMENDED PRESSURE DIFFERENTIAL BETWEEN THE PRESSURE
RELIEF VALVE SET PRESSURE AND THE BOILER OPERATING PRESSURE
SHOULD BE AT LEAST 10 PSI, OR 25% OF THE BOILER OPERATING
PRESSURE, WHICHEVER IS GREATER. FAILURE TO MAINTAIN THIS
OPERATING MARGIN MAY RESULT IN WATER LEAKAGE PAST THE S EAT AND
AN ACCUMULATION OF DEPOSITS ON THE SEATING SURFACE. EXCESSIVE
DEPOSITS MAY PREVENT THE VALVE FROM OPERATING PROPERLY, AND A
DANGEROUS PRESSURE BUILD-UP AND EQUIPMENT RUPTURE MAY RESULT.

MAINTENANCE AND TESTING

CAUTION! BEFORE TESTING, MAKE CERTAIN DISCHARGE PIPE IS PROPERLY
CONNECTED TO VALVE OUTLET AND ARRANGED TO CONTAIN AND SAFELY
DISPOSE OF BOILER DISCHARGE (SEE "INSTALLATION INSTRUCTIONS").

UNDER NORMAL OPERATING CONDITIONS A "TRY LEVER TEST" MUST BE
PERFORMED QUARTERLY. UNDER SEVERE SERVICE CONDITIONS, OR IF
CORROSION AND/OR DEPOSITS ARE NOTICED WITHIN THE VALVE BODY,
TESTING MUST BE PERFORMED MORE OFTEN. PRESSURE TEST ANNUALLY
PRIOR TO HEATING SEASON, AND AT THE END OF ANY NON-SERVICE
PERIOD.

TEST AT OR NEAR MAXIMUM OPERATING PRESSURE BY HOLDING THE
TEST LEVER FULLY OPEN FOR AT LEAST 5 SECONDS TO FLUSH THE VALVE
SEAT FREE OF SEDIMENT AND DEBRIS. THEN RELEASE LEVER AND PERMIT
THE VALVE TO SNAP SHUT.

IF LIFT LEVER DOES NOT ACTIVATE, OR THERE IS NO EVIDENCE OF
DISCHARGE, DISCONTINUE USE OF EQUIPMENT IMMEDIATELY AND CONTACT
A LICENSED CONTRACTOR OR QUALIFIED SERVICE PERSONNEL.

NEITHER CONBRACO INDUSTRIES, INC. NOR ITS AGENTS ASSUME ANY
LIABILITY FOR VALVES IMPROPERLY INSTALLED OR MAINTAINED.

DO NOT REMOVE THIS TAG!

INSTALLATION INSTRUCTIONS

MODEL RVW10, RVW30, & RVW60

1. INSTALLATION MUST BE PERFORMED BY QUALIFIED SERVICE
PERSONNEL ONLY.

2. THE BTU/HR OR LB/HR RATING OF THIS VALVE MUST EQUAL OR EXCEED
THAT OF THE EQUIPMENT TO WHICH IT IS INSTALLED.

3. DO NOT USE THIS VALVE ON A COAL OR WOOD BOILER HAVI NG AN
UNCONTROLLED HEAT INPUT.

4. INSURE THAT ALL CONNECTIONS, INCLUDING THE VALVE INLET, ARE
CLEAN AND FREE FROM ANY FOREIGN MATERIAL.

5. USE PIPE COMPOUND SPARINGLY, OR TAPE, ON EXTERNAL THREADS
ONLY.

6. DO NOT USE A PIPE WRENCH! USE PROPER TYPE AND SIZE WRENCH
ON WRENCH PADS ONLY.

7. THIS VALVE MUST BE MOUNTED IN A VERTICAL, UPRIGHT POSITION
DIRECTLY TO A CLEAN, TAPPED OPENING IN THE TOP OF THE BOILER
OR EQUIPMENT. UNDER NO CIRCUMSTANCES SHOULD THERE BE A
FLOW RESTRICTION OR VALVE OF ANY TYPE BETW EEN THE SAFETY
RELIEF VALVE AND THE PRESSURE VESSEL.

8. WARNING! DURING OPERATION, THIS VALVE MAY DISCHARGE LARGE
AMOUNTS OF STEAM AND/OR HOT WATER. THEREFORE, TO REDUCE
THE POTENTIAL FOR BODILY INJURY AND PROPERTY DAMAGE, A
DISCHARGE LINE MUST BE INSTALLED THAT:
A. IS CONNECTED FROM THE VALVE OUTLET WI TH NO INTERVENING
VALVE AND DIRECTED DOWNW ARD TO A SAFE POINT OF
DISCHARGE,
B. ALLOWS COMPLETE DRAINAGE OF BOTH THE VALVE AND THE
DISCHARGE LINE,
C. IS INDEPENDENTLY SUPPORTED AND SECURELY ANCHORED SO AS
TO AVOID APPLIED STRESS ON THE VALVE,
D. IS AS SHORT AND STRAIGHT AS POSSIBLE,
E. TERMINATES FREELY TO ATMOSPHERE WHERE ANY DISCHARGE
WILL BE CLEARLY VISIBLE AND IS AT NO RISK OF FREEZING,
F. TERMINATES WITH A PLAIN END THAT IS NOT THREADED,
G. IS CONSTRUCTED OF A MATERIAL SUITABLE FOR EXPOSURE TO
TEMPERATURES OF 375°F OR GREATER,
H. IS, OVER ITS ENTIRE LENGTH, OF A PIPE SIZE EQUAL TO OR
GREATER THAN THAT OF THE VALVE OUTLET .

USE ONLY SCHEDULE 40 PIPE FOR DISCHARGE. (DO NOT USE
SCHEDULE 80 PIPE OR CONNECTIONS). DO NOT CAP,
PLUG, OR OTHERWISE OBSTRUCT DISCHARGE PIPE OUTLE T!

9. SEE APPROPRIATE ASME BOILER AND PRESSURE VESSEL CODE FOR
ADDITIONAL INSTALLATION INSTRUCTIONS.
