Page 3: General
The Gas Safety (Installations & Use) Regulations 1988. Nu-way gas boosters are suitable for use with both natural and clean, dry manufactured gases, giving the performance shown on page 10. The maximum ambient temperature should not exceed 40°C. -
Page 4: Booster / Burner Operating Modes
Changeover to the standby booster in the event of a failure of the booster is automatic. Manual isolating valves and non-return valves (not supplied by Nu-way) must be fitted to comply with IGE/UP/2. -

Page 7: Installation Instructions
Institute of Gas Engineers Publication IGE/UP/2. It is recommended that Nu-way gas boosters are positioned as close to the combustion equipment as is reasonably possible, in non-hazardous atmospheres where the ambient temperature will not exceed 40°C, but must not be installed in governor or meter rooms. -
Page 8: Gas Booster Anti-Vibration Kit
Gas Booster Anti-Vibration Kit General The Nu-way gas booster anti-vibration kit is standard supply. For a twin duty standby unit, two kits will be required. Installation Flexible connections and anti-vibration mountings should be installed in accordance with Codes of Practice. -
Page 9: Gas Pressure Switches
GAS PRESSURE SWITCHES The booster is supplied with gas pressure switches (as required), they are either fitted to the rear of the control panel, or in the case of duty standby systems mounted on a bracket above the booster. The purpose of the switches is to monitor the inlet and outlet pressures. Adjustment of the switches is achieved by removal of the clear plastic cover and turning the dial to the required setting. -
Page 10: Maintenance
The relevant instructions given on page 7 should be consulted. When the fan assembly requires replacement the complete Nu-way unit must be substituted and fitted in accordance with the instructions supplied with the kit. Care must be taken not to over-tighten the bearing securing nuts as this can damage the fan chamber. -
Page 11: Belt And Pulley Replacements
Belt and Pulley Replacements When ordering spares the full data plate details should be supplied. To replace these items the following procedure should be adopted:- Switch off and isolate the booster power supply, remove the belt guard. Support the weight of the motor platform and remove the existing belt. Clean or replace the pulleys (see note below). -

Page 13: Gas Booster Reservoir
This will prevent nuisance tripping of the pressure switch due to transient pressure changes, but will ensure safe shutdown in the event of a drop in inlet pressure. A reservoir is available from Nu-way (Part No. T99-057E), contact Nu- way Sales Dept. -
Page 14: Slow Pressure Ramp Up And Speed Control Options
SLOW PRESSURE RAMP UP AND SPEED CONTROL OPTIONS INTRODUCTION The gas booster can be fitted with an inverter controller to provide Slow Pressure Ramp Up to reduce the pressure reduction on the upstream gas pipework and equipment. This device can be programmed to control the gas booster to ramp up to full speed from x seconds to y seconds. -
Page 15: Gb3160 / Gb3500 Vsd General Arrangement
GB3160 / GB3500 VSD GENERAL ARRANGEMENT SLOW PRESSURE RAMP UP INVERTER CONTROL AND OPERATION The function of the Slow Pressure Ramp Up inverter control system is to control the time taken for the gas booster to reach full speed. This is controlled by entering the required ramp up time in the controller (see SET UP PROCEDURE FOR DANFOSS VLT MICRO DRIVE- default set to 10 seconds). -
